WebAccording to the Gibbs Energy formula ΔG = ΔH − TΔS with a small unknown value of ΔH and a large negative value of ΔS, the value of ΔG will turn out to be positive. A positive ΔG indicates that the mixing of the hydrophobe and water molecules is not spontaneous. Formation of Hydrophobic Interactions The origin of the hydrophobic effect is not fully understood. Some argue that the hydrophobic interaction is mostly an entropic effect originating from the disruption of highly dynamic hydrogen bonds between molecules of liquid water by the nonpolar solute. A hydrocarbon chain or a similar nonpolar region of a large molecule is incapable of forming hydrogen bonds with water. Introduction of s…
