A square planar complex is formed by hybridisation of which atomic orbitals?

Answer: (b) spx py dx2 – y2 A square planar complex is formed when four orbitals of the central atom hybridize. In this case, the central atom is usually a metal, and the four orbitals that hybridize are two s orbitals and two p orbitals. The two s orbitals hybridize to form a single spx orbital and the two p orbitals hybridize to form two py and dx2 – y2 orbitals. Therefore, the correct answer is (b) spx py dx2 – y2.
