Question

In $s{p}^3{d}^3$ hybridisation, which orbitals are involved?

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

Answer 1

The correct option is A $d_{x^2-y^2}$, $d_{z^2}$, $d_{xy}$

The seven-coordinate polyhedron of maximum symmetry is the $D_{5h}$ pentagonal bipyramid with $s{p}^3{d}^3(xy,x^2-y^2,z^2)$ hybridization.
