I'm still having trouble with making MO diagrams, so much help would be appreciated. Thanks so much!
The basis for Lewis Acid/Base interactions can be derived from Molecular Orbital theory. The Lowest Unoccupied Molecular Orbital on the acid (Acid LUMO) will have the appropriate symmetry and similar energy to the Highest Occupied Molecular Orbital on the Lewis Base (Base HOMO). One of the better types of systems to demonstrate this is aminoborane complexes.
Use Models360 to build valence MO diagrams, quantitatively accurate, for both NH3 and BH3 on either side of the back of this sheet in landscape orientation. Leave room in the middle for an additional set of MOs.
Put the energy axis on the left in units of eV (-25 eV to 5 eV).
Label all MOs.
Circle frontier orbitals and draw pictures of them nearby.
Create a new set of MOs for the H3NBH3 adduct in the center of the page. Do your best to approximate the energy of the orbitals since H3NBH3 is not a molecule in Models360.
