CONCEPT:

Geometry of Xenon Compounds Based on Hybridization

• The geometry of xenon compounds can be predicted based on the hybridization of the central xenon atom and the presence of lone pairs.
• The Valence Shell Electron Pair Repulsion (VSEPR) theory is used to determine the arrangement of bonds and lone pairs around the central atom.
• The hybridization and molecular geometry of xenon compounds are as follows:
  • sp³ hybridization: Tetrahedral electronic geometry; molecular geometry depends on lone pairs.
  • sp³d hybridization: Trigonal bipyramidal electronic geometry; molecular geometry depends on lone pairs.
  • sp³d² hybridization: Octahedral electronic geometry; molecular geometry depends on lone pairs.
  • sp³d³ hybridization: Pentagonal bipyramidal electronic geometry.

EXPLANATION:

• A. XeO₃: Xenon is sp³ hybridized with one lone pair and three bonded oxygen atoms. This results in a pyramidal geometry.
  
• B. XeF₂: Xenon is sp³d hybridized with three lone pairs and two bonded fluorine atoms. This results in a linear geometry.
  
• C. XeOF₄: Xenon is sp³d² hybridized with one lone pair and five bonded atoms (four fluorine and one oxygen). This results in a square pyramidal geometry.
  
• D. XeF₆: Xenon is sp³d³ hybridized with one lone pair and six bonded fluorine atoms. This results in a distorted octahedral geometry.
  

• Match the compounds with their geometries:
  • A. XeO₃: II (sp³; pyramidal)
  • B. XeF₂: I (sp³d; linear)
  • C. XeOF₄: IV (sp³d²; square pyramidal)
  • D. XeF₆: III (sp³d³; distorted octahedral)

Therefore, the correct answer is: A-II, B-I, C-IV, D-III.
