Hydrogen Bonding

Strong type of intermolecular dipole-dipole attraction. A strong secondary interatomic bond which exists between a bound hydrogen atom (its unscreened proton) and the electrons of adjacent atoms. Occurs between hydrogen and fluorine, oxygen or nitrogen.

Hydrogen bonds are responsible for the unique properties of water and they loosely pin biological polymers like proteins and DNA into their characteristic shapes.
