Identify the incorrect statement for $\mathrm{PCl_5}$ from the following.

In this molecule, orbitals of phosphorous are assumed to undergo

sp^3d

hybridization.

The geometry of

\mathrm{PCl_5}

is trigonal bipyramidal.

\mathrm{PCl_5}

has two axial bonds stronger than three equatorial bonds.

The three equatorial bonds of

\mathrm{PCl_5}

lie in a plane.

Answer and worked solution

Official answer: C

Incorrect statement. In $\mathrm{PCl_5}$ the axial bonds are longer and weaker than the equatorial ones (more repulsion from the equatorial pairs).
