In the reaction

2 \mathrm{PCl}_{5} \rightleftharpoons \mathrm{PCl}_{4}^{+}+\mathrm{PCl}_{6}^{-}

, the change in hybridisation is from

Options

A $s p^{3} d$ to $s p^{3}$ and $s p^{3} d^{2}$
B $s p^{3} d$ to $s p^{2}$ and $s p^{3}$
C $s p^{3} d$ to $s p^{3} d^{2}$ and $s p^{3} d^{3}$
D $s p^{3} d^{2}$ to $s p^{3}$ and $s p^{3} d$

Correct answer

A. $s p^{3} d$ to $s p^{3}$ and $s p^{3} d^{2}$

Step-by-step solution

2 \mathrm{PCl}_{5} \rightleftharpoons \mathrm{PCl}_{4}^{+}+\mathrm{PCl}_{6}^{-}\uparrow s p^{3} d \quad \uparrow s p^{3} \quad \uparrow s p^{3} d^{2}
