Vedclass · Answer

(A) In the $CO$ molecule, the electronegativity difference suggests a dipole moment, but the actual dipole moment is very small $(0.11 \ D)$.This is because the $\sigma$-electron drift from $C$ to $O$ (due to the lone pair on $C$) is almost completely nullified by the back-donation of $\pi$-electrons from $O$ to $C$ through $\pi$-bonding.Thus, the net dipole moment is nearly zero, making it practically non-polar.

$CO$ is practically non-polar since
