Question

In which molecule sulphur atom is not ${sp}^3$-hybridized?

• A. $S{O}_4^{2-}$
• B. $S{F}_4$
• C. $S{F}_2$
• D. None of these

Answer 1

The correct option is B $S{F}_4$

$S{F}_4$ is not ${sp}^3$-hybridized

${SF}_4$ has ${sp}^{3}d$-hybridized sulphur atom. In molecule ${SF}_4$, there are five electron pairs which should lead to trigonal bi pyramidal structure. Out of the five electron pairs, one is a lone pair. This lone pair could occupy an axial position or an equatorial position.
