- Think of a high boiling point as more likely to be a solid/liquid at room temperature, meaning it has higher intermolecular forces. You know polarity will increase intermolecular forces; if you put a positive and negative charge next to each other of course they'll be attracted, increasing the chance that they'll stick together, raising the boiling point.London Dispersion Forces Definition. So we can say that covalent bond, ionic bond, coordination bond are the intra-molecular force of attraction which form within a molecule. The forces of attraction between molecules which hold them together are called the intermolecular force of attraction. These forces are weaker than intermolecular forces.
