Review Questions

• Explain how the molecular geometry of chlorine trifluoride is determined using the VSEPR theory.
  • According to the VSEPR theory, the molecular geometry of chlorine trifluoride is determined by the number of bonding electron pairs and non-bonding electron pairs around the central chlorine atom. The chlorine atom has five electron pairs in total: three bonding electron pairs with the fluorine atoms and one non-bonding electron pair. To minimize the repulsion between these electron pairs, the molecule adopts a trigonal bipyramidal geometry, with the three fluorine atoms occupying the equatorial positions and the lone pair of electrons occupying the axial positions.
• Describe the key features and applications of chlorine trifluoride that are relevant to its role in the context of hybrid atomic orbitals.
  • Chlorine trifluoride is an important compound in the study of hybrid atomic orbitals because its trigonal bipyramidal molecular geometry is a direct result of the hybridization of the central chlorine atom's atomic orbitals. Specifically, the chlorine atom undergoes $sp^3d$ hybridization, combining one $s$ orbital and three $p$ orbitals to form five hybrid orbitals that can accommodate the five electron pairs around the central atom. This hybridization and the resulting molecular geometry are essential for understanding the bonding and reactivity of chlorine trifluoride, which has applications in the production of uranium hexafluoride for nuclear fuel and weapons.
• Evaluate the importance of understanding the chemical properties and reactivity of chlorine trifluoride in the context of its role in the study of hybrid atomic orbitals and its practical applications.
  • Chlorine trifluoride is a crucial compound for understanding the principles of hybrid atomic orbitals, as its trigonal bipyramidal molecular geometry is a direct consequence of the $sp^3d$ hybridization of the central chlorine atom's atomic orbitals.
