Question

Nitrogen show weaker tendency for catenation than phosphorus why

Answer 1

As nitrogen atom is smaller, there is greater repulsion of electron density of two nitrogen atoms, which in turnweaken the N-N single bond and decreases the tendency of nitrogen toshow catenation. ... Thus higher the stability of single bond between the same atom more will be its affinity to undergo catenation.

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.
