Reading: CHP 5 Molecular Orbitals - Examples and Applications: 5.1 - 5.2.1


Learning Outcomes:

  • know conditions required to form MOs
  • be able to approximate the formation of molecular orbitals from atomic orbitals (LCAO) for simple homonuclear diatomics
    • MOs from s-orbitals
    • MOs from p-orbitals
  • understand some advantages (and disadvantages in using MOs over simple Lewis structures)
  • be able to produce the MO diagrams for diagrams
  • use the diagram to calculate bond order and multiplicity
  • identify the LUMO and HOMO in the diagram
  • use the diagrams to rationalize the relative stability of diatomics
