Sketch out a molecular orbital energy diagram for CO and place the electrons in the levels appropriate for the ground state. The AO ionization energies are O2s: 32.3 eV; O2p: 15.8 eV; C2s: 19.4 eV; and C2p: 10.9 eV. The MO energies follow the sequence (from lowest to highest) 1σ, 2σ, 3σ, 4σ, 1π, 5σ, 2π, 6σ. Connect each MO level with the level of the major contributing AO on each atom.
