Repulsion of solute by the solvent instead ofĪttractive forces at the site of organization Main consequence The hydrophobicĮffect is a unique organizing force, based on This could be the origin of one veryĬommon misconception that hydrophobic molecules Term hydrophobic (water-hating), which isĬommonly used for hydrocarbons, is highly Water a lipophobic (oil-hating) substance. In contrast, hydrophobes like water moleculesĪnd would like to maximize the contact with H2O Molecules are squeezed out of the aqueous Molecules into larger and larger aggregates.īecause of these entropic reasons, hydrophobic Will cause the aggregation of hydrophobic Whatever they can to minimize such contacts, i.e. Have to freeze in attempt to maintain a maximum Which are in direct contact with a hydrophobe

N-butane in water, but it is very unfavorableįrom an entropic perspective. Is actually enthalpically favorable to place

Temperature the equation for Gibbs free energy In the example of n-butane in water at room Liquid state is engaged in approximately 3 (accepting two andĭonating two) Each molecule of water in the Interaction between non-polar hydrophobicĮach molecule of water in the solid state isĮngaged in 4.0 hydrogen bonds. TheseĪre stronger than induced dipole-induced dipoleįorces (dispersion), the only possible type of Water molecules as they can interact with water Is a highly deceptive appearance! The vdw forceīetween two hydrocarbons is weaker than vdw forceīetween a hydrocarbon molecule and a water Molecules are placed in water, they appear to be Hydrophobic molecules? When two hydrophobic What does hydrophobic mean? What are examples of
