The shapes of\[S{{F}_{4}}\]and\[Xe{{F}_{2}}\]respectively are

A)  trigonal bipyramidal and trigonai bipyramidai

B)  see-saw and linear

C) T-shape and linear

D) square planar and trigonal bipyramidal

Correct Answer: B

Solution :

The shape of \[S{{F}_{4}}\] is see-saw as it contains four bond pairs and one lone pair. \[\text{K}{{\text{O}}_{\text{2}}}\]has \[\text{C}{{\text{O}}_{\text{2}}}\] hybridisation and linear geometry (due to the presence of 3 lone pairs) which is represented as
