Xenon does not form fluorides such as `XeF_(3)andXeF_(5)` Why ?

Text Solution

Verified by Experts

All the filled orbitals of Xe have paired electrons .the promotion of 1,2 or 3 electrons from the 5 p filled orbitals to the 5d vacant orbitals will give rise to 2,4 and 6 half -filled orbitals .Therefore , Xe can combine with even number of F - atoms but not with odd .
