Q. Which of the following is planar?
A) $XeF_{2}$
B) $XeO_{3}F$
C) $XeO_{2}F_{2}$
D) $XeF_{4}$
Explanation
(a)
$XeF_{2}$ molecule contains two bond pairs and three lone pairs in the outer-shell of central atom and thus its hybridisation is $sp^{3}d^{2}$ but to minimise the repulsive forces the three lone pairs occupy the equatorial position and the molecule becomes linear shape.
