The shape of `XeF_4` molecule and hybridisation of xenon in it are

A

a) tetrahedral and `sp^3`

B

b) square planar and `dsp^2`

C

c) square planar and `sp^3 d^2`

D

d) octahedral and `sp^3 d^2`

Text Solution

Verified by Experts

The correct Answer is:
C
In `XeF_4` the central atom, Xe, has eight electrons in its outermost shell. Out of these four are used for forming `sigma` bonds with F and four remain as lona pairs.
`XeF_4 implies 4 sigma` bonds +2 lone pairs
`implies 6` hybridised orbitals, `ie, sp^3 d^2` hybridisation
Since, two lone pairs of electrons are present, the geometry of `XeF_4` becomes square planar form octahedral.
