The shape of \[\text{XeO}{{\text{F}}_{\text{2}}}\]on the basis of VSEPR theory is

A)  sea saw       

B)  V-shaped

C)  trigonal planar

D)  T-shaped

Correct Answer: D

Solution :

 In \[\text{XeO}{{\text{F}}_{\text{2}}}\text{,}\]the central atom\[\text{Xe}\]has 3 bond pairs of electrons and 2 lone pairs of electrons. Thus, the central atom is \[s{{p}^{3}}d\]hybridised and its geometry should be trigonal bipyramidal. But due to the presence of two lone pairs, geometry becomes T-shaped (according to VSEPR theory).
