Reading: CHP 5 Molecular Orbitals for Larger Molecules: Sect 5.4.4-5.4.5


Learning Outcomes:

  1. understand the advantages (and disadvantages in using MOs over simple Lewis structures) particularly for larger molecules
  2. be able to produce a reducible representation for a set of atomic orbitals on the terminal atoms in a molecule such as BF3
  3. be able to use the MO diagram to explain some chemical and physical properties large molecules
    • estimate bond order for the B-F bond
    • identify the LUMO and HOMO in the diagram
    • explain Lewis acid-base acid-base properties of the molecule

Worked Example: Carbon Dioxide
