Consider of following values for enthalpy of vaporization (kJ/mol) of several organic substances:

(a) Use variations in the intermolecular forces operating in these organic substances to account for their variations in heats of vaporization.
(b) How would you expect the solubilities of these substances to vary in hexane as solvent? In ethanol? Use intermolecular forces, including hydrogenbonding interactions where applicable, to explain your responses.
