In this video we discuss hydrogen bonds. We cover how do hydrogen bonds form, the different elements that take part in hydrogen bonds, and why doesn't oil and water mix. What are hydrogen bonds? An attractive force called a hydrogen bond can exist between certain molecules. These bonds are weaker than ionic or covalent bonds, because it takes less energy to break these types of bonds, however, a large number of these bonds going on can exert a strong force. Hydrogen bonds are the result of an unequal charge distribution on a molecule, these molecules are said to be polar. If we look at a water molecule, we can see the oxygen atom shares electrons with 2 different hydrogen atoms. So, in total this molecule has 10 protons, 8 from oxygen and 1 each from the hydrogen atoms, and a total of 10 electrons, 2 shared between the oxygen atom and hydrogen atom number one, 2 shared between the oxygen atom and hydrogen atom number 2, and the other 6 non shared electrons from the oxygen atom. So, this water molecule is electrically neutral, but it has a partial positive side, the hydrogen side, and a partial negative side, the oxygen side of the molecule. The electrons are not shared equally within the molecule, as they have a higher probability of being found closer to the nucleus of the oxygen atom, giving that end a slightly negative charge. So, the hydrogen atoms end of the molecule will have a slightly positive charge. These charged ends weakly attach the positive end of one water molecule to the negative end of an adjacent water molecule. When water is in liquid form there a few hydrogen bonds, solid form, many bonds, and when water is steam or gas, there are no bonds, because the molecules are too far apart to form any bonds. Hydrogen bonds only form between hydrogen atoms that are covalently bonded, or bonds where electrons are being shared and not transferred, to an oxygen, nitrogen or fluorine atom. These bonds make water ideal for the chemistry of life. Hydrogen bonds are also important in the structure of proteins and nucleic acids, which we will cover in later videos. So, now we know that water molecules are polar, or have slightly positive and slightly negative ends, and in fact, many lipids, or fats and oils, are not polar. So their molecules share electrons equally in their bonds. So, these are nonpolar molecules. This means that when water and oil come together they do not form bonds with one another. Even when we try to mix them, the water molecules will eventually separate because their polar molecules are attracted to one another and will form hydrogen bonds, separating the water and the nonpolar oil molecules.

To see all my Chemistry videos, check out http://socratic.org/chemistry Hydrogen bonding can be so confusing, and in this video we talk about some common mistakes. Hydrogen bonds are intermolecular forces between molecules. They form because one atom has a high electronegativity, so it gets a partial negative charge, and the hydrogen gets a partial positive charge.

This chemistry video tutorial provides a basic introduction into hydrogen bonding. Hydrogen bonding occurs in molecules when hydrogen is attached to highly electronegative small atoms such as nitrogen, oxygen, and fluorine. Hydrogen bonds are very strong dipole dipole interactions. Molecules that contain hydrogen bonds such as water are very polar. Hydrogen bonds is one of the strongest types of intermolecular forces. This video contains a few examples and illustrations of hydrogen bonds in water and in HF.

Why is water essential for Life to exist on Earth? We are about 60% water - and there are some organisms that are as much as 90% water! What is so important about water? How does it support life? In this video, we discuss the special properties of water that make it the “Solvent of Life.” Chief among these properties is the extensive Hydrogen Bonding between water molecules that make water an extremely cohesive liquid (the molecules stick together). Due to the extensive hydrogen bonding, water has some emergent properties that impact life on Earth in many ways. These include: Cohesion Adhesion High surface tension High specific heat High heat of vaporization Ice Floats (Ice is less dense as a solid than liquid water) For each of these properties, we discuss how they impact living creatures on Earth. ❀❀❀❀❀❀❀❀❀❀ Our series on Biology is aimed at the first-year college level, including pre-med students. These videos should also be helpful for students in challenging high school biology courses. Perfect for preparing for the AP Biology exam or the Biology SAT.

We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program. Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class! The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival. It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences. Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth. About Ian Stuart (Email: [email protected]): The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world. Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths. Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

Imagine a box filled with hydrogen atoms. Like billiard balls on a pool table, atoms actually move, and they do it in straight lines until they hit something … like another hydrogen atom. Oh! See that? They stuck together. They’re not separate hydrogen atoms any more, but a pair of hydrogen atoms moving together. There goes another pair. 4.1 When atoms join up like this, scientists call it a molecule. And they call the join between them a chemical bond. Here comes another hydrogen atom crashing into the hydrogen molecule. But this time it doesn’t stick. Instead it just bounces off. Hydrogen atoms bond once, and that’s it. They’re just like that. Pretty quickly all the hydrogen atoms will collide and pair off into molecules. They will keep hitting each other, but they'll just bounce off. Scientists like to have a shorthand way of writing this molecule thingi. Here’s one way to show it, with the hydrogen symbols joined by a stick to show the chemical bond between the atoms. Another way is to write H2, with the little 2 after the H and a bit lower. A number written this way is called a subscript. What do you think the 2 stands for? It counts the number of hydrogen atoms in the molecule. Easy, heh! So when we have a balloon filled with hydrogen gas, it really contains trillions of trillions of H2 molecules. Let's do another thought experiment. We'll go back to our box filled with hydrogen atoms, but this time put an oxygen atom in there too. When a hydrogen atom crashes into an oxygen atom, they stick together. But wait, when another hydrogen atom hits, it also sticks to the oxygen. What about a third hydrogen atom? No, that’s if for oxygen. It can only make 2 bonds and then it’s done.

What is HYDROGEN BOND? What does HYDROGEN BOND mean? HYDROGEN BOND meaning - HYDROGEN BOND definition - HYDROGEN BOND explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom. These hydrogen-bond attractions can occur between molecules (intermolecular) or within different parts of a single molecule (intramolecular). Depending on geometry and environmental conditions, the hydrogen bond may be worth between 5 and 30 kJ/mole in thermodynamic terms. This makes it stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins. Intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have no hydrogen bonds. Intramolecular hydrogen bonding is partly responsible for the secondary and tertiary structures of proteins and nucleic acids. It also plays an important role in the structure of polymers, both synthetic and natural. In 2011, an IUPAC Task Group recommended a modern evidence-based definition of hydrogen bonding, which was published in the IUPAC journal Pure and Applied Chemistry. This definition specifies: The hydrogen bond is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X–H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which there is evidence of bond formation. An accompanying detailed technical report provides the rationale behind the new definition.

It is due to the electrostatic hydrogen bond, as explained in this film. Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Hydrogen_bond Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ A hydrogen bond is a partially electrostatic attraction between a hydrogen (H) atom which is bound to a more electronegative atom or group, such as nitrogen (N), oxygen (O), or fluorine (F)—the hydrogen bond donor—and another adjacent atom bearing a lone pair of electrons—the hydrogen bond acceptor. Hydrogen bonds can be intermolecular (occurring between separate molecules) or intramolecular (occurring among parts of the same molecule). Depending on the nature of the donor and acceptor atoms which constitute the bond, their geometry, and environment, the energy of a hydrogen bond can vary between 1 and 40 kcal/mol. This makes them somewhat stronger than a van der Waals interaction, and weaker than fully covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins. Intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weaker hydrogen bonds. Intramolecular hydrogen bonding is partly responsible for the secondary and tertiary structures of proteins and nucleic acids. It also plays an important role in the structure of polymers, both synthetic and natural... A ubiquitous example of a hydrogen bond is found between water molecules. In a discrete water molecule, there are two hydrogen atoms and one oxygen atom. Two molecules of water can form a hydrogen bond between them that is to say oxygen-hydrogen bonding; the simplest case, when only two molecules are present, is called the water dimer and is often used as a model system. When more molecules are present, as is the case with liquid water, more bonds are possible because the oxygen of one water molecule has two lone pairs of electrons, each of which can form a hydrogen bond with a hydrogen on another water molecule. This can repeat such that every water molecule is H-bonded with up to four other molecules, as shown in the figure (two through its two lone pairs, and two through its two hydrogen atoms). Hydrogen bonding strongly affects the crystal structure of ice, helping to create an open hexagonal lattice. The density of ice is less than the density of water at the same temperature; thus, the solid phase of water floats on the liquid, unlike most other substances. Liquid water's high boiling point is due to the high number of hydrogen bonds each molecule can form, relative to its low molecular mass. Owing to the difficulty of breaking these bonds, water has a very high boiling point, melting point, and viscosity compared to otherwise similar liquids... The number of hydrogen bonds formed by a molecule of liquid water fluctuates with time and temperature... https://en.wikipedia.org/wiki/Water#Polarity_and_hydrogen_bonding Since the water molecule is not linear and the oxygen atom has a higher electronegativity than hydrogen atoms, it is a polar molecule, with an electrical dipole moment: the oxygen atom carries a slight negative charge, whereas the hydrogen atoms are slightly positive... Because of its polarity, a molecule of water in the liquid or solid state can form up to four hydrogen bonds with neighboring molecules. These bonds are the cause of water's high surface tension and capillary forces. The capillary action refers to the tendency of water to move up a narrow tube against the force of gravity. This property is relied upon by all vascular plants, such as trees. The hydrogen bonds are also the reason why the melting and boiling points of water are much higher than those of other analogous compounds like hydrogen sulfide (H 2S). They also explain its exceptionally high specific heat capacity (about 4.2 J/g/K), heat of fusion (about 333 J/g), heat of vaporization (2257 J/g), and thermal conductivity (between 0.561 and 0.679 W/m/K). These properties make water more effective at moderating Earth's climate, by storing heat and transporting it between the oceans and the atmosphere...

2.2 Water: Polarity of Water and Hydrogen Bonds Understanding that: - Hydrogen bonding and bipolarity explain the cohesive, adhesive, thermal and solvent properties of water - Structure of water causes it to be polar and thus cause hydrogen bonds to form in between them
Views: 8692 Alex Lee
Hydrogen Bonds are found between simple molecules that contain either H-F, H-O or H-N bonds. Two factors affect the effectiveness of Hydrogen bonds and hence the boiling point of the molecule. The first factor is extensiveness of the Hydrogen bond, or the average number of Hydrogen bonds each molecule can form. If a molecule can form more Hydrogen bonds, then during boiling more Hydrogen bonds need to be broken which results in a higher boiling point. The second factor is the polarity of the H-F, H-O and H-N bond. In H-F bond is the most polar hence the hydrogen bond that results from this is the strongest, while H-N bond is the least polar which results in the weakest hydrogen bond. To learn more about each of these factors and when to consider them, watch this video tutorial now!

Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really wants to have 8 to have a full shell. The hydrogens have one outer shell electron, but want to have two. The atoms share their electrons, forming covalent bonds. So all three atoms have full outer shells, and create a water molecule. Water has two covalent bonds. In water, the bonding electrons spend most of their time nearer the oxygen atom, because it is more ELECTRONEGATIVE. This means that it is electron withdrawing. As the negatively charged electrons are nearer the oxygen atom, the oxygen atom becomes a little bit negative itself, while the hydrogens become a little positive. This is called delta positive and delta negative. Water doesn’t just have any old covalent bonds; it has what we call POLAR COVALENT bonds and is a POLAR molecule. This is really important as it affects how water behaves and reacts with other elements. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

The polar nature of water gives it some important properties. It allows things to dissolve in it. It has a high specific heat capacity. It’s got a high heat of vaporisation. Water molecules are cohesive meaning they can stick to each other. They are adhesive meaning they can stick to other things. Water has a high surface tension. And because hydrogen bonds force solid water to form in a crystalline structure, ice is less dense than water and therefore it floats.

For further reading Hydrogen Bonding, Please click on the link given below .... http://vedupro.blogspot.in/2013/02/hydrogen-bonding-h-bonding.html HYDROGEN BONDING -- H Bonding The force of interaction between Hydrogen atoms which is already covalently bonded and more electronegative atom present in the system is known as Hydrogen Bonding. In 1920, Latimer and Rodebush introduced the idea of "Hydrogen Bond" to explain the nature of association in liquid state of substance like water, hydrogen fluoride, ammonia, formic acid etc. In a Hydrogen Compound, when hydrogen is bonded to highly electronegative atom (such as F, O, N) by a covalent bond, the electron pair is attracted towards electromagnetic atoms so strongly that a dipole results i.e., one end carries a positive charge (H-end) and other end carrier a negative charge......

You drink it, clean with it, and swim in it, but do you really understand it? Take a few minutes and learn about how awesome water really is. Subscribe: http://bit.ly/2wJ0DHa TheCrazyChosenOne: https://www.youtube.com/channel/UC_Oz1ntBqRGuhZ5g9MvgyqA Learn more about water! https://owlcation.com/stem/5-Properties-of-Water https://socratic.org/questions/what-are-some-examples-of-properties-of-water https://science.howstuffworks.com/environmental/earth/geophysics/h2o7.htm Now, on to water aka dihydrogen monoxide aka H2O. Water is made up of one oxygen atom, and two hydrogen atoms. And looks something like this. This structure makes water a very polar molecule. Without going into the beautiful details, Oxygen has a net negative charge while the opposite ends with the hydrogens have a net positive charge. This allows water molecules to form hydrogen bonds and gives water many of its other properties. Cohesion and Adhesion are two such properties. Cohesion is water’s attraction to itself. The hydrogen bonds that I mentioned facilitate this. This is also why water has surface tension, allowing bugs to walk on it. Additionally, cohesion keeps water a liquid at moderate temperatures instead of a gas. Adhesion is water’s attraction to other surfaces. Water will adhere to anything it can form a hydrogen bonds with. This is the reason for capillary action, where water climbs up a narrow glass tube. Another property of water is it’s high heat capacity. Heat capacity is a substance ability to absorb heat. More accurately, it’s the amount of energy needed to raise one gram of a substance by one degree celsius. This allows water to absorb temperature changes and keep air temperature at moderate levels. Which is pretty cool… Finally, water is known as the universal solvent, meaning that a wide range of substances can be dissolved in it. This includes hydrophilic and polar molecules like sugars and salts. Substances that generally don’t dissolve in water are hydrophobic, like oils. So now you know a little more about the properties of H2O, and bare in mind, we only covered a portion of water’s amazing properties, so be sure to check the links in the description to learn more. And, as always throw any questions in the comment section! Now, I want to give a shoutout to one of my subscribers, TheCrazyChosenOne. The channel is linked below. It’s a gaming channel with a lot of Fortnite recently, and who doesn’t love some Fortnite gameplay, am I right? Easy listening, enjoyable watching. The channel is not limited though, it features a wide variety of game from Minecraft to Call of Duty. So check it out, and if you like the content, give it some love with likes, comments, and a sub.

3.3.4 Explain how a DNA double helix is formed using complementary base pairing and hydrogen bonds. Nitrogenous bases from two single strands are joined using the complimentary base pairing rule. Adenine with Thymine (using two hydrogen bonds) and Cytosine with Guanine (using three hydrogen bonds). A DNA double helix is formed firstly when a nucleotide joins with another nucleotide by a covalent bond forming a single strand. The nitrogenous bases from this single strand then bond to nitrogenous bases from another single strand (by the complimentary base pairing rule and using hydrogen bonds as stated above) in order to form a double helix. Note that the two strand are antiparallel to each other (running in opposite directions as indicated by the arrows).

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about. If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law. -- Table of Contents Bonds Minimize Energy 01:38 Covalent Bonds 03:18 Ionic Bonds 05:37 Coulomb's Law 05:51 -- Want to find Crash Course elsewhere on the internet?

Hydrogen bonding is an intermolecular or intramolecular attraction that occurs between molecules with hydrogen bond donors and molecules with hydrogen bond acceptors. Hydrogen bond donors are molecules that have a hydrogen attached to an electronegative atom (for example, hydroxyls or amines). Hydrogen bond acceptors are molecules that have a lone pair of electrons located on an electronegative atom (for example, oxygen, nitrogen, or fluorine). Hydrogen bonds are not as strong as covalent and ionic bonds but are stronger than van der Waals interactions. Hydrogen bonding is responsible for the high boiling point of water and is important for the organization of complementary chains of base pairs in DNA and RNA. ---------- Chemistry tutoring on Chegg Tutors Learn about Chemistry terms like Hydrogen Bonding on Chegg Tutors.

I'm strongest as a teacher when I'm working one-on-one and my favorite part of teaching is "diagnosing" where a student's thinking might be leading them astray (or ahead!)I got my Masters at Harvard in Applied Math, focusing on statistics and advanced mechanics/physics applied to biology. I taught and tutored Organic Chemistry, Precalculus, Calculus, proof-based Linear Algebra and Real Analysis, and Intro to Applied Math (for majors) at Harvard. I also work with student writing for classes, projects and graduate applications as a tutor in my undergraduate house. I've tutored everything from 5th grade math to competitive math teams to graduate school pure math and engineering. I've worked with Master's Engineering students studying for the TOEFL alongside high school sophomores in my Saturday volunteer creative writing classes, and I've tutored undergraduates at Harvard and helped develop curriculum in proof-based math and numerical experimentation-driven freshman physics. EXTRACURRICULAR INTERESTS I'm from Brooklyn, NY. I'm a city kid who could stare at the stars all night, which I do when I visit my family in rural Canada. I love biking, choral singing, performing poetry, teaching in all settings and with all people, and crisis management and education for mental health. I'm always looking to get into new art forms, learn new languages and pursue things where my gaps lead me. I also have difficulty keeping a straight face for more than a few minutes (or a paragraph) at a time. Want to book a private lesson with Jamie B.?

Let’s talk about the electronegativity and charge density of Nitrogen and Chlorine and also how Hydrogen bonding influences the corresponding atoms… Sounds serious? Then, let’s look at the same but with a twist. Let’s try to understand them by using a pizza! We at Byju's Classes strongly believe that a spirit of learning and understanding can only be inculcated when the student is curious, and that curiosity can be brought about by creative and effective teaching. It is this approach that makes our lectures so successful and gives our students an edge over their counterparts.
