The dipole moment of a molecule can be predicted by looking at the molecule's structure and the location of the dipoles within the molecule. When a molecule has no dipole moment, it will be nonpolar. A molecule with a dipole moment will be polar.
No side of the molecule has more negative or positive charge than another side, and so the molecule is nonpolar: A water molecule is polar because (1) its O-H bonds are significantly polar, and (2) its bent geometry makes the distribution of those polar bonds asymmetrical.
