Answer: Polar molecules have an uneven distribution of electrons that cause one end of the molecule to have a positive charge and the other to have a negative charge. ... This means that in a polar bond, the electronegativity of the atoms will be different. For nonpolar bonds the electronegativity of the atoms will be equal.
