Question

In which of the following molecules $S$ atom does not assume $s{p}^3$ hybridisation?

• A. $S{O}_4^{2-}$
• B. $S{F}_4$
• C. $S{F}_2$
• D. $S_8$

Answer 1

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

In $S{O}_4^{-2}$ molecule, central atom sulfur has $s{p}^3$ hybridisation.

In $S{F}_4$ molecule, central atom sulfur has $s{p}^{3}d$ hybridisation.

In $S{F}_2$ molecule, central atom sulfur has $s{p}^3$ hybridisation.

In $S_8$ molecule, central atom sulfur has $s{p}^3$ hybridisation.

So answer is B.
