Witryna(which only has London dispersion forces) has a higher boiling point than acetone (which has dipole-dipole and London dispersion forces). Therefore, the London dispersion forces must be greater than the dipole-dipole forces in this case. 13. ΔH fus is the energy needed for water to go from a solid to a liquid and ΔH vap is the energy WitrynaAboutTranscript. A liquid’s vapor pressure is directly related to the intermolecular forces present between its molecules. The stronger these forces, the lower the rate of evaporation and the lower the vapor pressure. Created by Sal Khan.
