So what is the question?

Explanation:

Generally we represent the carbon monoxide as "sp-hybridized"sp-hybridized. Such a scheme places formal charges on the oxygen and carbon atoms:

""^(-):C-=O:^(+):CO:+

There are 5 valence electrons around CC, hence it has a formal negative charge, but only 5 around OO, hence it has a formal positive charge. Such a designation can help rationalize why carbon monoxide typically binds to a metal centre via the carbon, e.g. [Ni(CO)_4][Ni(CO)4].
