Question

The d-orbitals involved in $s{p}^3{d}^2$ or $d^{2}s{p}^3$ hybridisation of the central metal ion are

• A. $d_{x^2-y^2}$
• B. $d_{xy}$
• C. $d_{yz}$
• D. $d_{z^2}$

Answer 1

Answer: (A), (D)

The correct options are
A $d_{x^2-y^2}$
D $d_{z^2}$

The d-orbitals involved in s$s{p}^3{d}^{2}or{d}^{2}s{p}^3$ hybridization of the central metal ion are $d_{x^2-y^2}$ and $d_{z^2}$ respectively.
The linear combination of a 4s-orbital with three 4p-orbitals
($4p_x,4p_y,and4p_z$) and two 3d-orbitals
($3d_{x^2-y^2}$ and $3d_{z^2}$) results in six
$s{p}^3{d}^2$-orbitals of identical shape, but different orientation in space.
The geometry is octahderal.
The examples include $S{F}_6$ and $P{F}_6^{-}$
