How does the intermolecular interaction affect the magnitude of enthalpy change during phase transformation?
Asked by Topperlearning User | 14 Aug, 2014, 12:45: PM
answered-by-expert Expert Answer

The strength of intermolecular interaction determines the magnitude of enthalpy change. For example in water there is strong intermolecular interaction in the form of hydrogen bond and in acetone the intermolecular interaction is weak dipole-dipole interaction. Hence enthalpy of vaporization is greater in case of water.
