In the structure of SF 4 , the lone pair of electrons on S is in.

In the structure of SF4, the lone pair of electrons on S is in.
  1. Equatorial position and there are two lone pair - bond pair repulsions at 90°.
  2. equatorial position and there are three lone pair - bond pair repulsions at 90°.
  3. axial position and there are three lone pair - bond pair repulsion at 90°.
  4. axial position and there are two lone pair - bond pair repulsion at 90°.

Solution

In SF4, The lone pair is in an equatorial position, and there are two lp—bp repulsions. Hence, the following arrangement shown below is more stable.

The shape shown in the following figure is described as a distorted tetrahedron, a folded square or a see-saw.
