Chapter 9, Problem 105CP
Carbon monoxide (CO) forms bonds to a variety of metals and metal ions. liS ability to bond to iron in hemoglobin is the reason that CO is so toxic. The bond carbon monoxide forms to metals is through the carbon atom:
a. On the basis of electronegativities, would you expect the carbon atom or the oxgen atom to form bonds to metals?
b. Assign formal charges to the atoms in CO. Which atom would you expect to bond to a metal on this basis?
c. In the MO model, bonding MOs place more electron density near the more electronegative atom. (See the HF molecule in Figs. 4-54 and 4-55.) Antibonding MOs place more electron density near the less electronegative atom in the diatomic molecule. Use the MO model to predict which atom of carbon monoxide should form bonds to metals.

The expected bond angle around the Nitrogen is ~109°; the
experimentally determined angle is 123°. What does this suggest about the C- N bond?
(hint: consider possible resonance structures)
Both carbon and oxygen are nonmetals, having 4 and 6 valence electrons, respectively. In this type of bond, a
central atom must be identified.
Carbon and Oxygen- Carbon Dioxide
Bonds must be formed depending on the number of bonding and non-bonding electrons.
Non-bonding electrons are called lone pairs, they are the ones left at the end of bonding. The illustration of

If you investigate the illustration, you will notice that carbon atom is double bonded to two oxygen atoms. The
reason for that is because carbon atom must also have complete eight electrons, therefore octet rule must also be
followed at the same time.
