Flexi Says: A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A polar molecule is called a dipole because it has two poles. Similarly, a polar bond itself can be called a dipole. For molecules with more than two atoms, the molecular geometry must also be taken into account when determining if the molecule is polar or nonpolar. If the dipoles are of equal strength, they are oriented pointing outward, and they cancel each other out, resulting in nonpolarity. If the dipoles are of unequal strength, they point inward and do not cancel each other out, resulting in polarity.
