    Draw the molecular orbital (MO) diagrams for \(N_2\) and \(CO\). Use your MO diagrams to explain which molecule is a better \(\pi\)-acceptor when coordinated to a transition metal.


    Draw reasonable Lewis structures (including resonance) and predict the molecular geometry for the following molecules:

    1. \(NO_2\)
    2. \(ClF_3\)
    3. \(OF_2\)
    4. \(NO\)
    5. \(XeO_3\)
    6. \(POCl_3\)
    7. \(XeF_2\)
    8. \(SF_4\)


    Indicate if following molecules are X or L type ligands. Label each with \(\sigma\)-donor, \(\pi\)-acceptor, or \(\pi-\)donor?

    1. \(Ph_3P\)
    2. \(Cy_3P\)
    3. \(SCN^-\)
    4. \(CH_3COO^-\)
    5. benzyne
    6. \(NO\)


    Draw and name all possible coordination modes (hapticity) of a cyclopentadienyl ligand to a transition metal.


    For the following complexes, provide the formal oxidation state, \(d^n\) configuration, and total valence electron count for the metal.
