Cell Biology/Membranes/Hydrophobicity. Hydrophobicity literally means fear of water. The opposite of this is hydrophilicity which means love of water. These two terms denote the properties of molecules or parts of molecules to bond with water (hydrophilicity) or reject water (hydrophobicity). This effect is seen when one puts a drop of oil on water.
The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in aqueous solution and exclude water molecules.This occurs because interactions between the hydrophobic molecules allow water molecules to bond more freely, increasing the entropy of the system.The word hydrophobic literally means water-fearing, and it describes the segregation and apparent repulsion between water and nonpolar substances.The hydrophobic effect is responsible for the separation of a mixture of oil and water into its two components.his occurs because interactions between the hydrophobic molecules allow water molecules to bond more freely, increasing the entropy of the system.
