Question

For the complexes showing the square pyramidal structure, the d-orbitals involved in the hybridisation is :

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

Answer 1

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

When five ligands are attached to the central metal atom, the central metal atom undergoes $ds{p}^3$ hybridization.

When $d_{z^2}$ orbital is involved in the hybridization, the geometry is trigonal bipyramidal.

When $d_{x^2-y^2}$ orbital is involved in the hybridization, the geometry is square pyramidal.

Hence the correct option is A.
