A polar molecule is one that is uncharged, but has an asymmetric internal distribution of charge, leading to partially positive and partially negative regions. III. Water interacts differently with charged and polar substances than with nonpolar substances because of the polarity of its own molecules IV. Water molecules are polar, with partial positive charges on the hydrogen, a partial, and negative charge on the oxygen.
