The next two questions investigate how Molecular Orbital Theory and Lewis Theory view carbon monoxide. —. Draw a molecular orbital energy diagram (showing all of the bonding and antibonding molecular orbitals and their respective energies) for CO. Use the Molecular Orbital energy levels for B2 , C2 and N 2 for the CO molecule. —. Calculate the bond order for CO from the molecular orbital energy diagram. —. Is CO paramagnetic or diamagnetic? ------------- b. Draw the Lewis structure for CO. —. Calculate the formal charge on each atom in CO. —. Draw the dipole for CO. —. Calculate the oxidation numbers for the carbon and oxygen atoms in CO. —. Formal charges, dipoles, and oxidation numbers are different ways of understanding the charges on covalently-bonded atoms. They tend to agree or be similar. At least in some ways, they disagree for CO. Formal charge guidelines assume that all bonding electrons are shared evenly between the two bonded atoms. Oxidation number guidelines assume that…
