Scholarcy highlights

  • The low solubility of low‐molecular weight alkanes in water is not due to the necessity of breaking H‐bonds in water upon introducing the solute
  • The hydrophobic effect is essentially due to this extension of the territory of the mobile order
  • Contrary to the assumptions of multicomponent theories, the combinatorial entropy of the mixture is practically not affected by the presence of the H‐bonds
  • From the value of the combinatorial entropy derived in part two, and neglecting all enthalpic effects one derives an equation predicting the solubilities of alkanes in water ϕB = exp
