AbstractA general theory of hydrophobic hydration and pairwise hydrophobic interaction has been developed in the last years. The main ingredient is the recognition that: (a) cavity creation (necessary to insert a solute molecule into water) causes a solvent-excluded volume effect that leads to a loss in the translational entropy of water molecules; (b) the merging of two cavities (necessary to form the contact minimum configuration of two nonpolar molecules) causes a decrease in the solvent-excluded volume effect and so an increase in the translational entropy of water molecules. The performance of the theoretical approach is tested by reproducing both the hydration thermodynamics of xenon and the thermodynamics associated with the formation of the contact minimum configuration of two xenon atoms, over a large temperature range.

Enthalpy And Entropy

The solvation of argon in 10 different solvents at room temperature is analysed in terms of the theoretical framework developed by Lee. In order to perform calculations, we used the approach devised by Pierotti and firmly validated by Lee's theory. The fair agreement between the experimental and the calculated values of Δ G. Δ H. , and Δ S. is carefully analysed. It proves that the excluded volume effect, due to cavity creation in the solvent, opposes the solubility process. This effect in water is exaggerated by the small size of the water molecules and is the cause of hydrophobicity. The qualitative difference between water and hydrazine with regard to the solvation enthalpy and entropy changes is rationalized on the basis of the contributions arising from the structural reorganization in the two solvents on solute insertion.Key words: hydrophobic hydration, cavity creation, structural solvent reorganization.
