Question

A square planar compound or complex is formed by hybridisation 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. $s,p_x,p_z,d_{xy}$

Answer 1

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

The hybridisation of square planar compound or complex is $ds{p}^2$ or $s{p}^{2}d$. All the orbitals of $s,p,d$ involved in it needs to be in one plane. So, the set of orbitals are $s,p_x,p_y,d_{x^2-y^2}$.
