Carbon monoxide - Wikipedia

Carbon monoxide has a computed fractional bond order of , indicating that the "third" bond is important but constitutes somewhat less than a full bond. Thus, in valence bond terms, – C≡O + is the most important structure, while :C=O is non-octet, but has a neutral formal charge on each atom and represents the second most important resonance contributor.
