Which pair of species is isostructural and also has the same hybridisation of the central atom?
AXeOFX4 and XeOX4
BXeFX2 and SFX2
CXeOX3 and SOX3
DXeFX4 and IClX4X−
Answer: D
Both XeFX4 and IClX4X− have 4 bond pairs and 2 lone pairs: square planar, sp3d2. XeO3 is pyramidal (sp3) but SOX3 is trigonal planar (sp2); XeF2 is linear but SFX2 is bent; XeOF4 is square pyramidal but XeO4 is tetrahedral.
