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.
, PhD Candidate in Chemical Engineering. 1  A ânon-polarâ molecule is one that has a small or zero dipole moment. The overall dipole moment of a molecule is the vector sum of the individual dipoles of each bond, which in turn is determined by the polarity of the atoms in each bond.
