Hi
Here's your answer
1)Carbon monoxide, CO, is isoelectronic to nitrogen, N2. a. Draw a Lewis structure for CO that satisfies the octet rule. What are the formal charges? b. Assume the MO diagram for N2 can be used to describe the MOs of CO. What is the predicted bond order for CO? Does the bond order from the MO diagram match the bond order in your Lewis structure? c. Experimentally, it is found that the highest energy electrons in CO reside in a -type molecular orbital. Is that observation consistent with your prediction? d. If two electrons were added to CO to make CO2-, what will the MO diagram look like? Sketch the expected MO diagram, and predict if CO2- is diamagnetic or paramagnetic. With what small neutral homo-diatomic molecule is CO2- isoelectronic: Li2, Be2, B2, C2, N2, O2 or F2?
2)For the molecular skeleton above, fill in the double and triple bonds, and place the lone pairs appropriately. Determine the VBT hybrid for each C, N and O atom in the structure.

dpssuman2002:
srry but these are the structures of other compounds and also I think they are not the resonance structures
