Question

Why does nitrogen show catenation property is less than phosphorus?

Answer 1

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.

Answer 2

Hey !!

Nitrogen show catenation property is less than phosphorous because of N ---- N single bond is weaker than P ----- P single bond.

Good luck !!
