In the number of lone pairs on are respectively
2, 3, 1
1, 2, 3
4, 1, 2
3, 2, 1
As learnt in
Structure of Xenon hexafluoride -
Distorted octahedral and hybridisation is Sp3d3
- wherein
Xe2F2 has sp3 d2 hybridisation and total number of valance electrons of Xe=8, two electrons are shared with 21 atoms and 6 are left in 3 lone pairs.
Similarly, Xe2F4 has sp3 d2 hybridisation, 4 electrons or shared in bonds and 4 are left in 2 lone pairs and X2F6 and sp3 d3 hybridisation, 6 electrons are shared in bonds and 2 are lone pair.
Xe has 8 valence electrons
XeF6 : 6 bond pairs, 1 lone pair
XeF4 : 4 bond pairs, 2 lone pairs
XeF2 : 2 bond pairs, 3 lone pairs
