The correct answer is (A) : Equatorial position and there are two lone pair – bond pair repulsions at 90º
SF4 → sp3d hybridisation.
The lone pair of electrons on S is in equatorial position and there are two lone pair-bond pair repulsions at 90°.
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
