Abstract: Deviations from ideality in solution enthalpies of solutes are explained by hydrophobic hydration. The extent of this type of hydration is expressed by means of two methods. Experimental results obey previously proposed group contribution concept for evaluation of enthalpic effect of hydropho bic hydration and the obtained methylene group contribution is in good agreement with that obtained previously from the data on other hydropho­bic homologous series.
