Thermodynamic properties of aqueous solutions of hydrophobic solutes - Wen, W.-Y. (Elsevier)
The existence of hydrophobic hydration is well established. Examples are found for aqueous systems containing purely nonpolar groups (e.g., rare gases, alkanes and perflouroalkanes), poly-functional solutes (e.g., alcohols, ethers and ketones), and ionic solutes (e.g., tetraalkylammonium and azoniaspiroalkane ions). Influence of solute shape on the surrounding water structure is subtle but of particular interest. The 'structure promotion' effect in dilute aqueous solutions of hydrophobic groups is now firmly established, but the quantitative details are still incompletely understood. Recent advance in understanding the nature of hydrophobic hydration is made by Frank who pointed out that the hydrophobic hydration is not the cause of the low solubility of nonpolar gases in water.Hydrophobic bonding, which denotes the tendency of non polar groups in water to attract each other, is concentration dependent and not well characterized quantitatively. Several types of examples will be given in which the details of such interactions have been worked out.
