Chemistry - CHEMICAL BONDING Question with Solution | TestHub

In the classical hybridisation scheme assumed, d_(x²-y²) is used for sp³d² and sp³d³, not the usual sp³d set. XeF₅⁻ has seven electron domains; XeF₅⁺, PCl₆⁻ and IF₅ each have six, so those four qualify. SF₄ has five and XeO₃ four. Count 4. This is a curriculum orbital convention; modern hypervalent bonding does not require substantial d-orbital hybridisation.
