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

A)  sea saw                              

B)  V-shaped

C)  trigonal planar

D)  T-shaped

Correct Answer: D

Solution :

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