Question
Which one of the following is planar?
A.
$$Xe{F_4}$$
B.
$$Xe{O_4}$$
C.
$$Xe{O_3}F$$
D.
$$Xe{O_3}{F_2}$$
Answer :
$$Xe{F_4}$$
Solution :
Structure of $$Xe{F_4}$$ is as follows
It involves $$s{p^3}{d^2}$$ hybridisation in $$Xe - {\text{atom}}{\text{.}}$$ The molecules has square planar structure. $$Xe$$ and four $$F - {\text{atoms}}$$ are coplanar. The lone pairs are present on axial positions, minimise electron pair repulsion.
