Why xeo3 and xeo4 has sp3 hybridization?

Answer 1

XeO3 is sp3 since Xe has three bonds to oxygens and one long pair of electrons. These 4 together conclude a tetrahedral shape and hybridize as sp3 where 1 of the four electrons reside in the s and each p orbital. so, s gets one leaving 3 for the p orbital, thus sp3.

XeO4 is kind of the same except it is bonded to 4 Oxygens and those 4 bonds spread out into the s and p orbitals in such that one is in the s and 3 in the p orbitals. together they make sp3.

Now why are they both the same is because long pair electrons in this case count as a bond so the XeO3 that had one long pair electron in fact is like if it had 4 bonds.

I hope this enlightened you and helped.
