Why does nitrogen show catenation properties less than phosphorus?

Text Solution

Verified by Experts

Catenation depends on the strength of the interatomic bond. The N-N bond strength `(159 kJcdotmol^(-1))` is much weaker than P - P bond strength `(213 kJcdotmol^(-1))`. Therefore, catenation property of nitrogen is less than that of phosphorus.
