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

$$\mathrm{PCl}_5$$ possesses two different $$\mathrm{Cl}-\mathrm{P}-\mathrm{Cl}$$ bond angles

All five $$\mathrm{P}-\mathrm{Cl}$$ bonds are identical in length

$$\mathrm{PCl}_5$$ exhibits $$s p^3 d$$ hybridisation

$$\mathrm{PCl}_5$$ consists of five $$\mathrm{P}-\mathrm{Cl}$$ (sigma) bonds
