The bond is then said to be polar. The term polar molecule can mean two things: (1) simply that there are polar bonds present in the molecule, (2) that the molecular structural arrangement of bonds and electron lone pairs gives rise to a permanent molecualr dipole moment.eport Abuse. A polar molecule has a difference in electronegativity between atoms across the entire molecule. The differently charged atoms are called dipoles. A commonly used example is water, H2O. The oxygen molecule has a high electronegativity compared to the hydrogen molecules, so it exhibits a negative dipole.
If the molecule contains polar bonds that are of equal polarity and point in opposite directions, they cancel out, leaving the molecule nonpolar. If there is a net direction to the polar bonds, then the molecule is polar. Carbon dioxide is a good example to see this in. The C-O bonds in the molecule are polar, but because the molecule is linear and the C-O bonds point in opposite directions, the molecule is nonpolar overall. The polar bonds cancel one another out. The same thing applies to carbon tetrachloride. The C-Cl bonds of the molecule are polar, but because they all symmetrically point to the four corners of a tetrahedron, they cancel one another out. In a molecule like water, however, the polar O-H bonds do not cancel one another out perfectly.
