The hybridization of P in PCl5 is sp3d
The Lewis structure of PCl5 is
According to VSEPR theory, a molecule with five bonding pairs must have both a trigonal bipyramidal electron geometry and molecular geometry.
The P atom needs five orbitals to form the five P-Cl b.onds
It has a 3s and three 3p orbitals, so it must use one of its 3d
orbitals to form the fifth bond. These orbitals are hybridized to form five
sp3d orbitals that (surprise!) just happen to point in the right directions to form a trigonal bipyramid.
