In P=O bond, π bond is formed by the sidewise overlapping of which orbitals?

1. pπ-pπ orbitals
2. pπ-dπ orbitals
3. dπ-dπ orbitals
4. sπ-pπ orbitals

Correct answer: pπ-dπ orbitals

Solution

In the P=O bond, the π bond is formed by the sidewise overlapping of a p orbital from oxygen and a d orbital from phosphorus, leading to a pπ-dπ interaction.
