Concept introduction:

Hydrogen bonding occurs when a hydrogen atom is covalently bonded to $\text{O,}\text{F,}\text{N}$ and is attracted to lone pair of electrons present on another $\text{O,}\text{F,}\text{N}$. Hydrogen bonding is the strongest intermolecular interactions while van der Waal forces are the weakest.
