Quizplus · Accepted Answer

Propane is a nonpolar molecule, so it only experiences dispersion forces as its intermolecular interaction. Dispersion forces are the result of temporary dipoles formed due to electron movements within the molecule. These temporary dipoles cause the attraction between nearby molecules. Therefore, the strongest type of intermolecular interaction attracting molecules of propane to each other is dispersion forces.
