Question

The molecule which possesses both sp3 and sp3d2 hybridisation is (A) solid PCl5 (B) gaseous PCl5 (C) PCl4 (D) PCl6

Tardigrade Admin · Accepted Answer

Solid P C l5 ionises as 2 PCl 5 leftharpoons PCl 4++ PCl 6- PCl 4+is tetrahedral with P undergoing s p3 hybridisation P C l6-is octahedral with P undergoing s p3 d2 hybridisation.

Q. The molecule which possesses both $s p^{3}$ and $s p^{3} d^{2}$ hybridisation is

solid $PC l_{5}$

gaseous $PC l_{5}$

$PC l_{4}$

$PC l_{6}$

Solid $PC l_{5}$ ionises as
$2 PC l_{5} ⇌ PC l_{4}^{+} + PC l_{6}^{-}$
$PC l_{4}^{+}$ is tetrahedral with $P$ undergoing $s p^{3}$ hybridisation
$PC l_{6}^{-}$ is octahedral with $P$ undergoing $s p^{3} d^{2}$ hybridisation.
