Question

What is the experimental bond angles of $SF_{4}$ 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)

$SF_{4}$ : $sp^{3}d$ hybridisation with one lone pair providing repulsion.
Therefore, bond angles change from $90 \rightarrow 89^\circ $ (apical ) and from $120$ $ \rightarrow $ $117^\circ $
