Question

A square planar complex is formed by hybridization of which atomic orbitals :

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

Answer 1

The correct option is B $s,p_x,p_y,d_{x^2-y^2}$

A square planar complex is formed by hybridization of $s,p_x,p_y,d_{x^2-y^2}$ atomic orbitals . All these orbitals lie in the xy plane. Four ligands also lie in the xy plane. This results in maximum overlap.
