True. Carbon monoxide (CO) is a nonpolar molecule. This is because the electronegativity difference between carbon and oxygen is not large enough to create a significant dipole moment. In a CO molecule, the carbon and oxygen atoms share a triple bond, which consists of one sigma bond and two pi bonds. The linear shape of the molecule and the symmetrical distribution of electrons result in a net dipole moment of zero, making CO a nonpolar molecule.
