Carbon monoxide, CO, is isoelectronic to N2., (a) Draw a Lewis structure for CO that satisfies the octet rule., (b) Assume that the diagram in Figure can be used to describe the MOs of CO. What is the predicted bond order for CO? Is this answer in accord with the Lewis structure you drew in part (a)?
Figure The energy-level diagram for atomic and molecular orbitals in NO.
(c) Experimentally, it is found that the highest-energy electrons in CO reside in a σ type MO. Is that observation consistent with Figure? If not, what modification needs to be made to the diagram? How does this modification relate to Figure ?

(d) Would you expect the π2p MOs of CO to have equal atomic orbital contributions from the C and O atoms? If not, which atom would have the greater contribution?
