Xenon compounds are among the most frequently tested for VSEPR and hybridisation. XeF2: 3 lone pairs + 2 bond pairs = SN 5, sp3d, linear. XeF4: 2 lone pairs + 4 bond pairs = SN 6, sp3d2, square planar (lone pairs occupy opposite axial positions). XeF6: 1 lone pair + 6 bond pairs = SN 7, sp3d3, distorted octahedral. XeO3: 1 lone pair + 3 bond pairs (each Xe=O counts as 1 sigma for SN) = SN 4, sp3, trigonal pyramidal. XeOF2: 1 lone pair + 3 bond pairs = SN 5, sp3d, T-shaped (lone pairs in equatorial). XeO2F2: 1 lone pair + 4 bond pairs = SN 5, sp3d, see-saw. Key trap: XeO4 has SN = 4 with 0 lone pairs, so it is sp3, tetrahedral.
