Question

XeOF₄ involves ______ hybridisation and is ______ in shape.

Answer 1

XeOF₄ involves sp³d² hybridisation and is square pyramidal in shape.

Explanation:

The Xe atom in XeOF₄ undergoes sp³d² hybridisation in its third excited state. It forms four σ-bonds with fluorine atoms and one with oxygen, while one lone pair remains on xenon. This gives the molecule a square pyramidal structure.
