Q. The type of hybridisation in $XeF_{4}$ is
A) $dsp^{2}$
B) $sp^{3}d$
C) $sp^{3}d^{2}$
D) $sp^{3}d^{3}$
Explanation
(c)
Electronic configuration of Xe in ground state
[image:4_image171.emf]
Electronic configuration of Xe in excited state
[image:4_image172.emf]
Electronic configuration of Xe in $XeF_{4}$
[image:4_image173.emf]
Note The expected geometry of $XeF_{4}$ is octahedral. On account of the fact that lp-lp repulsion > lp-bp repulsion, there is some distortion octahedral geometry with two lone pair of electrons. In other words, it has a square planar geometry.
