Identify the incorrect statement about $\mathrm{PCl}_5$.

1. $\mathrm{PCl}_5$ possesses two different $\mathrm{Cl}-\mathrm{P}-\mathrm{Cl}$ bond angles
2. All five $\mathrm{P}-\mathrm{Cl}$ bonds are identical in length
3. $\mathrm{PCl}_5$ exhibits $s p^3 d$ hybridisation
4. $\mathrm{PCl}_5$ consists of five $\mathrm{P}-\mathrm{Cl}$ (sigma) bonds

Solution

It is $s p^3 d$ hybridised with axial to equatorial angle of $90^{\circ}$ and equatorial bond angles of $120^{\circ}$. It has five $\mathrm{P}-\mathrm{Cl}$ sigma bonds. Axial bonds are longer than equatorial bonds.
