Solubilities and hydrophobic interactions in aqueous solutions of monoalkylbenzene molecules

Solubilities of a series of monoalkylbenzene molecules in water were determined spectroscopically at several temperatures. The standard free energies of transferring these solutes from the gas into the liquid phase were calculated. From these data we have estimated the hydrophobic interaction between a methane molecule and the various alkyl residues of these solutes.
