Vedclass · Answer

(A) The central atom $S$ in $SF_{4}$ has $5$ electron pairs ($4$ bond pairs and $1$ lone pair),resulting in $sp^{3}d$ hybridization.According to $VSEPR$ theory,the lone pair occupies the equatorial position in a trigonal bipyramidal geometry to minimize repulsion.In the equatorial position,the lone pair experiences repulsion from two axial bond pairs at $90^{\circ}$ and two equatorial bond pairs at $120^{\circ}$.Therefore,there are two lone pair-bond pair repulsions at $90^{\circ}$.
