How do they work? Neopentane molecules are the most compact of the three, offering the least available surface area for intermolecular contact and, hence, the weakest dispersion forces. Intermolecular and Ionic Forces Introduction: Molecules are attracted to each other in the liquid and solid states by intermolecular, or attractive, forces. To check our work, the boiling points ought to increase with stronger intermolecular forces and thus higher surface area. This type of force can be thought of simple dipole induction and it is much weaker than those present in molecules where there is a high electronegativity difference in the atoms making up the molecule.
