In SF_4 molecule, lone pair of electrons occupies equatorial position

1.	In SF_4 molecule, lone pair of electrons occupies equatorial position but not axial position why?
Answer» Solution : In a the LP is PRESENT at AXIAL position so THER are threelp - bp repulsions at `90^(@)`. In b the lp is present at equatorial position, and t here are only two lp-bp repultions at `90^(@)`.Hence arrangement b. is more stable i.e. lp occupies EQUITORIAL position.
