Answer:

So what is the question?

Explanation:

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

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

There are 5 valence electrons around #C#, hence it has a formal negative charge, but only 5 around #O#, 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]#.
