Polar vs. Nonpolar - STLCC.edu

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.
