Answer
Xenon Compounds: Geometry and Hybridization
1. Xenon Trioxide (XeO₃)
Hybridization: sp³
Geometry: Pyramidal
Explanation: Xenon forms three bonds with oxygen atoms and retains one lone pair, resulting in a pyramidal geometry due to electron pair repulsion.
2. Xenon Difluoride (XeF₂)
Hybridization: sp³d
Geometry: Linear
Explanation: With five electron pairs (2 bonding, 3 lone), the linear shape results from lone pairs occupying equatorial positions in a trigonal bipyramidal structure.
3. Xenon Oxyfluoride (XeOF₄)
Hybridization: sp³d²
Geometry: Square pyramidal
Explanation: XeOF₄ contains six electron regions (5 bonding, 1 lone pair). The lone pair causes a distortion from perfect octahedral to square pyramidal geometry.
4. Xenon Hexafluoride (XeF₆)
Hybridization: sp³d³
Geometry: Distorted octahedral
Explanation: XeF₆ has seven electron pairs (6 bonding, 1 lone), where the lone pair distorts the ideal octahedral structure.
