Carbon monoxide (CO) is a poisonous compound due to its ability to bind to strongly to $\mathrm{Fe}^{2+}$ in the hemoglobin molecule. The molecular orbitals of $\mathrm{CO}$ have the same order as those of the $\mathrm{N}_2$ molecule.
Compare the bond order of $\mathrm{CO}$ predicted from the Lewis structure with that from molecular orbital theory.
