In which of the following molecules the central atom has two lone pairs of electrons?

• A. $S{F}_4$
• B. $Br{F}_5$
• C. $S{O}_2$
• D. $Xe{F}_4$

Answer 1

Answer: (D)

The structure of $Xe{F}_4$ is square planar with two positions occupied by lone pairs. It has $s{p}^3{d}^2$ hybridization and two lone pairs of electrons.
