Xenon does not form fluorides such as `XeF_(3)` and `XeF_(5)` -why?

Text Solution

Verified by Experts

All the filled orbitals of Xe have paired electrons. When one, two or three electrons are promoted from 5p - orbitals to the 5d -orbitals, two four and six half-filled orbitals are obtained. So, Xe can combine with only even but not odd number of F atoms. Hence, it cannot form `XeF_(3)` and `XeF_(5)`
