Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Hydrogen bond is an electrostatic attractive force between a covalently bonded hydrogen atom of one molecule and an electronegative atom like ( as F, O, or N) of other molecule. A hydrogen bond is an electrostatic attractive force and not a normal chemical bond. It is very weak ($2–10kcal/mol$) compared to a covalent bond (strength $50–100kcal/mol$).

In intermolecular hydrogen bonding, two or more molecules of the same or different substances are linked to form a polymeric aggregate. Intramolecular hydrogen bonding is also called chelation, as it involves ring formation.
