Find out total number of $p π - d π$ bonds present in any one of its structures in case of $PO_{4}^{3 -}$

Answer:

Solution:

The phosphate ion PO₄³⁻ has 4 equivalent resonance structures.

In each resonance structure, there is one P=O double bond and three P−O⁻ single bonds.

The P=O double bond contains one pπ−dπ bond (as per the traditional bonding model).

Therefore, any one resonance structure contains only one pπ−dπ bond.

Correct Answer: 1
