Why does nitrogen show catenation proper...

Why does nitrogen show catenation properties less than phosphourus?

Text Solution

Verified by Experts

Due to smaller size, the lone pair of electrons on the .N. - atoms repel the bond pair of .N-N. bond. In contrast, because of comparatively larger size of P, the lone pair of electrons on .P. atoms do not repel the bond pair of P-P bond tò the same extent. As a result, .N-N. single bond is weaker than .P. -P,.P. -P single bond. Consequently nitrogen shows little tendency for fatenation while .P. has a distinct tendency for catenation:
