The frontier orbitals are the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). Example: Methylene belongs to the C2v point group. The HOMO and LUMO have, respectively, s-type (A1) and p-type (B2) symmetry and are separated by about 1 eV. Symmetric and antisymmetric combinations of these orbitals give the C-C bonding and antibonding orbitals of ethylene (ethene, C2H4). Ethene belongs to the D2h point group.
Compounds that contain fewer valence electrons than valence ...
