Question

The type of hybridization involved in octahedral complex is :

• A. $s{p}^3{d}^2$
• B. $d^{2}s{p}^3$
• C. both A and B
• D. none of these

Answer 1

The correct option is C both A and B

Option (C) is correct. The hybridisation in octahedral complexes are $d^{2}s{p}^3$ or $s{p}^3{d}^2$.

All the complex ions having a coordination number of central metal atom as six show octahedral geometry. This octahedral geometry arises due to $d^{2}s{p}^3$ or $s{p}^3{d}^2$ hybridisation of the central metal atom or ion. The type of hybridisation (i.e. $d^{2}s{p}^3$ or $s{p}^3{d}^2$) depends on the no. of unpaired or paired electrons present in the complex ion.

Octahedral complexes in which the central atom is $d^{2}s{p}^3$ are called inner -orbital octahedral complexes while octahedral complexes in which the central atom is $s{p}^3{d}^2$ are called outer -orbital octahedral complexes.
