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 16hydrides 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.

Hydrogen bonding. Hydrogen bonding is considered to be the driving factor that has a significant effect on the biological activity of the compound. Our experts can quantify the strength of hydrogen bonds by establishing a QSAR model.
CHEMICAL SCIENCES AT BijuDepartment of OrganicChemistry, ... Organic chemistry is all about breaking carbon-hydrogen (C-H) bonds and substituting them with other molecules to make new desired compounds.
The positions of the hydrogen atoms resolved by the two techniques depended on the type of bonds between hydrogen atoms ... Resolving hydrogen atoms in small organic molecules depending on chemical bond ...
... hydrogen ... "However, the H2 covalent bond is one of the strongest in chemistry, and the pressure required to push hydrogen nuclei close enough to break the molecular bond is far higher than expected.
“We believe this strong interlayer interaction is primarily due to the chemistry of the hydrogen bond,” Lou said. “Hydrogen bonds are universal and occur in many systems.
