Question

Is $s{p}^3{d}^2$ hybridization the same as $d^{2}s{p}^3$ hybridization?

Answer 1

$s{p}^3{d}^2$ hybridization is the mixing of s, p and d atomic orbitals of the same electron shell to form $s{p}^3{d}^2$ hybrid orbitals. There, one s atomic orbital, three p atomic orbitals and two d atomic orbitals mix with each other. This mixing results in six hybrid orbitals of same size and shape but different from their orientation.

$d^{2}s{p}^3$ hybridization is the mixing of s and p atomic orbitals of the same electron shell with d orbitals of another electron shell to form $d^{2}sp{p}^3$ hybrid orbitals. This hybridization results in six hybrid orbitals.

Hence, $s{p}^3{d}^2$ and $d^{2}s{p}^3$ are not same.
