Carbon monoxide exhibits an exceptionally small dipole moment despite the significant electronegativity difference between carbon and oxygen, rendering it practically nonpolar.

The analysis

The retrieved literature (specifically papers 0 and 2) explicitly confirms that carbon monoxide has an extremely small dipole moment (~0.122 D), supporting the claim that it is practically nonpolar despite the electronegativity differences between carbon and oxygen.
