Within a molecule each polar bond has a bond dipole; A polar molecule always contains polar bonds, but some molecules with polar bonds are nonpolar. Polar Molecule. A molecule in which the bond dipoles present do not cancel each other out and thus results in a molecular dipole.(see below). Cancellation depends on the shape of the molecule or Stereochemistry and the orientation of the polar bonds. A result of the bond dipoles in a molecule. Examples: CO2 is a linear molecule with 2 bond dipoles that are equal and oppositely directed therefore the bond polarities cancel and the molecule is nonpolar.
