Question

What is the experimental bond angles of $S{F}_4$ molecule?

• A. $120^{\circ },180^{\circ }$
• B. $45^{\circ },118^{\circ }$
• C. $117^{\circ },92^{\circ }$
• D. $89^{\circ },117^{\circ }$

Answer 1

Answer: (D)

$S{F}_4$ : $s{p}^{3}d$ hybridisation with one lone pair providing repulsion.
Therefore, bond angles change from $90\to 89^{\circ }$ (apical ) and from $120$ $\to$ $117^{\circ }$
