Question

The shape of $Xe{O}_2{F}_2$ is :

• A. Trigonal Planar.
• B. See-saw.
• C. Square Planar.
• D. Tetrahedral.

Answer 1

The correct option is B See-saw.


The molecules assume different geometries based on the number of bond pairs/lone pairs in the valence shell of the central atom. The pi electrons are not involved in deciding the geometry of the molecule.
$Xe{O}_2{F}_2$ has the general formula $A{B}_{4}L$
It has 4 bonding pairs, and one lone pair. The electronic geometry is of type Trigonal Bipyramidal and the shape is See-Saw.
