    Draw the molecular orbital diagram for the following molecules or ions.
    1. (C_2)^2-
    2. (O_2)^2+

    What is the electron configurations of these molecules or ions?
    What is the bond order for each?
    Identify HOMO and LUMO for each.

    See attachment for solution. Molecular orbital diagrams are identified with respect to two types of notation.

    Bond order = (Number of bonding electrons - antibonding electrons) / 2 Hence for the C2 ion, bond order = (10-4)/2 = 3 For the O2 ion, bond order =(10-4) / 2 = 3 So bond order is the same for both ions.

    The HOMO's are the highest occupied orbitals. For C2 ion it is the sigma 2p, for O2 ion it the pi 2p. The LUMO's for both ions are the pi star 2p orbitals.
