$P-P$ single bond is weaker than $P \equiv P$ bond.

Vedclass · Answer

(B) Nitrogen forms a stable $N \equiv N$ triple bond due to effective $p\pi - p\pi$ overlapping,which is possible because of its small size. In the case of phosphorus,the atomic size is larger,making $p\pi - p\pi$ overlapping ineffective. Therefore,phosphorus prefers to form three $P-P$ single bonds rather than one $P \equiv P$ triple bond. As a result,phosphorus exists as $P_4$ molecules where each phosphorus atom is linked by single bonds.
