Question

Why does nitrogen change show catenation property less than phosphorus?

Answer 1

because nitrogen has small size compare to phosphorus and also due to high elctronegativity .

Answer 2

Answer:

Catenation is much more common in phosphorous compounds than in nitrogen compounds. This is because of the relative weakness of the N−N single bond as compared to the P−P single bond. Since nitrogen atom is smaller, there is greater repulsion of electron density of two nitrogen atoms, thereby weakening the N−N single bond.
