Learning objectives for this unit are to:

Derive molecular orbital energy diagrams for homonuclear and heteronuclear diatomic molecules, taking into account atomic orbital overlap and mixing of molecular orbitals
Predict the bond orders for homonuclear and heteronuclear diatomic molecules and ions, and correlate bond lengths, strengths, and stabilities of molecules with bond order
Predict the magnetic properties of molecules (diamagnetic/paramagnetic) based on the MO diagram
Identify the HOMO and LUMO on an MO diagram
Explain the origin and consequences of sp mixing
