The strength of $\mathrm{P} \pi-\mathrm{d} \pi$ bonding in $\mathrm{E}-\mathrm{O}(\mathrm{E}=\mathrm{Si}, \mathrm{P}, \mathrm{S}$ and Cl$)$ follows the order

(a)Si-O > P-O > S-O > Cl-O

(b)$\mathrm{P}-\mathrm{O}>\mathrm{Si}-\mathrm{O}>\mathrm{S}-\mathrm{O}>\mathrm{Cl}-\mathrm{O}$

(c)S-O > Cl-O > P-O > Si-O

(d)$\mathrm{Cl}-\mathrm{O}>\mathrm{S}-\mathrm{O}>\mathrm{P}-\mathrm{O}>\mathrm{Si}-\mathrm{O}$

Answer

Answer: D ✓ checked by 4AB · confidence high

Explanation

pπ–dπ bonding to oxygen strengthens as the d orbitals contract and match oxygen 2p better: Cl–O > S–O > P–O > Si–O.
