Question

a.) Draw an energy-level diagram for the valence molecular orbitals of CO. Include the relevant atomic orbitals in your diagram. Clearly label each molecular orbirals (e.g.?2, ?2p, etc) and fill in the appropriate number of electrons. Use the same energy order as the neutral O2 molecule. b.) Is CO paramagnetic or diamagnetic? What is the bond order of CO? c.) Draw a Lewis structurefor CO. Does this match the predicted bond order? d.) CO can react with OH- to form the formate ion, HCO2-. Draw the best possible Lewis structure for the formate ion. Include any non-zero formal charges and resonance if appropriate. Describe the bonding in terms of sigma and/or pi bonds, discussing the orbitals involved in bond formation, and describing any delocalization if appropriate.

Explanation / Answer

diamagnetic bond order = 2.5 Lewis Structure
