7.59 Explain why in spite of nearly the same electronegativity, nitrogen forms hydrogen bonding while chlorine does not.

7.59

Both chlorine and nitrogen have almost the same electronegativity values, but chlorine rarely forms hydrogen bonding. This is because in comparison to chlorine, nitrogen has a smaller size and as a result, a higher electron density per unit volume. Hence nitrogen forms hydrogen bonding more readily.

Chlorine has larger atomic size as compared to nitrogen and so has lower electron density per unit volume. Hence chlorine does not readily form hydrogen bonding.
