Although nitrogen and chlorine have very nearly same electronegativity yet nitrogen forms hydrogen bonding while chlorine does not. Why?

Text Solution

Verified by Experts

Due to bigger size of CI as compared to N, electron density per unit volume on N is higher than that on CI. As a result, N can attract the H atoms of `H_(2)O` more strongly than CI. Thus, N forms H-bonds but CI does not.
