A molecule with polar bonds must be a polar molecule in all cases.

Question

Quizplus · Accepted Answer

While polar bonds are necessary for a molecule to be polar, it is possible for some molecules with polar bonds to be nonpolar overall. This depends on the geometry of the molecule and whether the polar bonds cancel each other out. For example, carbon dioxide (CO2) has two polar carbon-oxygen bonds, but the molecule is linear and the bond dipoles cancel each other out, making the molecule nonpolar.
