For each of the three oxides CO2, SO2 and XeO3, make a three-dimensional sketch of the molecule and clearly indicate which one (s) is (are) polar. Dipole-dipole interaction occurs whenever two polar molecules get near each other. Check out a sample textbook solution. Oxygen is more electronegative than hydrogen, so when the atoms bond, oxygen exerts a stronger pull on the molecule’s electrons. Refund Policy, 11 A nonpolar covalent bond is where 2 nonmetal atoms of the same electronegativity exhibit an equal sharing of electron pair while a polar covalent bond is where 2 nonmetal atoms of different electronegativity exhibit unequal sharing of electron pair.
