COCl2 is a polar molecule because the dipole between the carbon and the chlorine atoms is not equal to the dipole between the carbon and oxygen atoms. However, these charges are not canceled out when there is an asymmetric distribution of electrons. Cl2 (Chlorine) is nonpolar in nature because of its linear symmetrical shape and it consists of two chlorine atoms having equal electronegativity. SO2 is polar and it is because of the difference in electronegativity between sulfur and oxygen atoms. So the O end will have a σ+, and the end containing the two F's will have a σ-. Although the carbon and oxygen differ in their electronegativity due to which C=O bond is polar, the polarity of both opposite C=O bonds get canceled by each other due to symmetrical shape and result in a nonpolar molecule with zero dipole moment. Is SO2 polar or nonpolar? The bond in which equal sharing of electrons is done by both atoms is a nonpolar bond because, in such molecules, charge density on both atoms is the same resulting in a nonpolar molecule. Polarity of molecules can only be predicted on an individual basis. The greater the difference in electronegativity more will be the polarity of the molecule. There are 3 lone pairs of electrons on each bromine and two lone pairs on the oxygen.
