Hydrogen Bonding and Common Mistakes. If you liked this video, please subscribe to my channel by clicking on the YouTube button.

The most common mistake I see with hydrogen bonding is the misunderstanding of the relative strengths of the intermolecular forces. Most people mistake hydrogen bonding for the strongest intermolecular bond, when hydrogen bonding is just the strongest form of dipole-dipole attraction. The two strongest types of intermolecular bonds are the ion-induced dipole and the ion-dipole attractions.

Hydrogen bonding has also been found to be responsible for the secondary, tertiary, and quaternary structures of proteins and nucleic acids. A hydrogen bond occurs when a single hydrogen atom is fused to an electronegative atom.Hydrogen bonds are found in nucleic acids between base pairs and between water molecules. This type of bond also forms between hydrogen and carbon atoms of different chloroform molecules, between hydrogen and nitrogen atoms of neighboring ammonia molecules, between repeating subunits in the polymer nylon, and between hydrogen and oxygen in acetylacetone.Hydrogen bonding in organic molecules containing nitrogen. Hydrogen bonding also occurs in organic molecules containing N-H groups - in the same sort of way that it occurs in ammonia. Examples range from simple molecules like CH 3 NH 2 (methylamine) to large molecules like proteins and DNA.


The hydrogen bonding which takes place within a molecule itself is called intramolecular hydrogen bonding. It takes place in compounds containing two groups such that one group contains hydrogen atom linked to an electronegative atom and the other group contains a highly electronegative atom linked to a lesser electronegative atom of the other group.A hydrogen bonding is a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.These bonds are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

Hydrogen bonds formed in this way are responsible for some surprising properties: water has hydrogen bonding, which is why pond-skater insects can walk on its surface, why you can place about 40 drops of water on a single small coin (try it!), why ice floats when being solid we'd expect it to be more dense than water and sink, and why water has a high boiling point compared with the hydrides.

Hydrogen-bonding. Hydrogen bonds b are medium strength attractive intermolecular or intra-molecular forces. hydrogen-bonding () occurs when an atom of hydrogen is attracted by rather strong forces to two (groups of) atoms instead of only one, such that it may be considered to be acting as a bond between them ().They are dynamic (flickering) bonds, usually breaking on a picosecond time-scale.

Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible.This essay will examine the water molecule in order to ascertain how it brought about Earth's successful ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms.

DNA transfers hereditary information down generations and controls the production of proteins. Hydrogen bonds hold together the complementary base pairs in the DNA strand. Hydrogen bonds are easily broken which is an important feature for DNA replication. DNA replication is.

Hydrogen Bonding. Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

Examples of Hydrogen Bonds.Here is a list of molecules that exhibit hydrogen bonding: water (H 2 O): Water is an excellent example of hydrogen bonding.The bond is between the hydrogen of one water molecule and the oxygen atoms of another water molecule, not between the two hydrogen atoms (a common misconception).

Hydrogen bonding and drug designs The extent of solubility of a solute depends on its hydrophilic nature. A molecule is more soluble if it can form numerous hydrogen bonds with its water solvent.1 Hydrophobic interactions between hydrophobic regions of the binding site of a ligand and its lipophilic surfaces are important predictors of its interactions in a biological system, which may affect.
