WebHowever, despite having polar bonds, CO2 is a nonpolar molecule. This is because the two polar bonds in CO2 are arranged symmetrically around the carbon atom, with the oxygen atoms on opposite sides of the carbon atom. This results in the dipole moments of the two polar bonds canceling each other out, leaving no net dipole moment for the molecule. WebDipole moments occur when there is charge isolation. It can appear in an ionic bond between two ions, or in a covalent bond between atoms; dipole moments result from variations in the electronegativity. The larger the difference in electronegativity, the larger is the moment of the dipole.
