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) \[Xe{{F}_{4}}\]

Correct Answer: D

Solution :

 The structure of \[\text{Xe}{{\text{F}}_{\text{4}}}\]is square planar with two positions occupied by lone pairs. It has \[\text{s}{{\text{p}}^{\text{3}}}{{\text{d}}^{\text{2}}}\]hybridization and two lone pairs of electrons.
