Q.
The number of unshared valence electron pairs in $ XeF_2 $ is
AMUAMU 2015The p-Block Elements - Part2
Solution:
$XeF_2$ has linear structure.
It involves $sp^3d$ hybridisation on xenon which adopts trigonal bipyramidal geometry in which three positions are occupied by lone pairs. Because of the symmetrical arrangement of three lone pairs (each at an angle of $120^{\circ}$), the net repulsion on the $Xe—F$ bond pairs is zero.
Thus, $XeF_2$ has linear geometry
