MCQ (Single Correct Answer)

The shape of XeO2F2 molecule is

A
trigonal bipyramidal.
B
square planar.
C
tetrahedral.
D
see-saw.

Explanation

The electronic configuration of Xe is 5s2 5p6; and that of Xe in excited state is 5s2 5p5 5d1. The hybridisation is sp3d and geometry is see-saw. The actual shape is trigonal bipyramidal but due to the preaence of lone pair it gets distorted to see-saw structure.
