Polarity of Molecules and Strength
(The page may take a minute to load and configure the molecules.)
- The more polar a molecule is the stronger it will be able to attract to other molecules.
- The most common way for a molecule to be more polar is to have more polar covalent bonds, creating more polar regions where dipole-dipole attractions can occur.
More Polar Regions = Stronger Overall Dipole-Dipole Attraction Between Molecules |

The
more polar molecule forms more of the stronger dipole-dipole attractions. Both molecules form about the same London Dispersion attractions.
