Chemistry - CHEMICAL BONDING Question with Solution | TestHub

In ${\mathrm{PCl}}_5$, phosphorous undergoes ${\mathrm{sp}}^3\mathrm{d}$ hybridization and has trigonal bipyramidal geometry. It has two axial chlorine atoms \& three equatorial chlorine atoms bonded to the central P. Hence bond angles for axial are $90^{\circ },\mathrm{Cl}-\mathrm{P}-\mathrm{Cl}$ \& for equatorial Cl-P-Cl it is $120^{\circ }$.
