What is the hybridisation of Xe in XeO3

Ans: Xe is the central atom.

Because O is a bivalent group, there is no monovalent group connected to the centre atom.

Number of valency electrons = 8

Charge = 0

n=V+M±C2

M is the number of monovalent atoms that are bonded to a single central atom.

C = charge of the radical

n=82

n = 4

As a result, Xe hybridisation in  XeO3 is sp3.
