#Unit 1. Structure and Function of Biomolecules

A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.

Hydrogen bonds are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

Two Requirements for Hydrogen Bonding:

First molecules has hydrogen attached to a highly electronegative atom (N, O, F) called as (hydrogen bond donor)

Second molecule has a lone pair of electrons on a small highly electronegative atom (N, O, F) called as (hydrogen bond acceptor)
