NEET UG CHEMISTRY MCQ: CHEMICAL BONDING & MOLECULAR STRUCTURE

Option A ($\mathrm{P in PCl_3}$) is correct because both $POCl_3$ and $PCl_3$ have phosphorus as the central atom with three bonding pairs and one lone pair (or a double bond and two single bonds in $POCl_3$), resulting in $sp^3$ hybridization.
