# What orbital hybridization is expected for the central atom in a molecule with a square planar geometry ? A) sp3d B) sp3 C) sp2 D) sp3d2

The answer is D) $s {p}^{3} {d}^{2}$.
According to VSEPR Theory, a square planar molecular geometry corresponds to an $A {X}_{4} {E}_{2}$ molecule.
In this case, the central atom will have 6 hybridized orbitals, which corresponds to an $s {p}^{3} {d}^{2}$ hybridization.
