It is So beacause CO has a dipole because bonds of different atoms originate, generally, asymmetrical distributions of charge. ... Thus, in CO carbon is more electronegative. Polar molecules are polar because they have permanent non-symmetrical charge distributions..hope you get it,,thanbk you
The electronegativity of oxygen is 3.44 and for carbon it is 2.55 with a difference of 0.89. That is not a trivial difference. It translates to a bond that has 32% ionic character. The low dipole moment is more a result of the bonding electron distribution rather than electronegativity difference.
hope it helped.....☺️
