Question

What is the hybridization of Phosphorus Trichloride?

• A. ${sp}^3$
• B. ${sp}^2$
• C. $sp$
• D. None of these

Answer 1

The correct option is A ${sp}^3$

The hybridization of ${PCl}_3$ is ${sp}^3$. Phosphorus has five electrons in its outermost shell. Thus it forms three sigma bonds with three neighbouring Chlorine atoms. The remaining two electrons remain as a lone pair on Phosphorus atom. Thus these three sigma bonds and one lone pair, make this molecule ${sp}^3$ hybridized.
