WebDescription. . Principle. Fats and oils are insoluble in water, and very sparingly soluble in cold alcohol. Fats are highly soluble in organic solvents such as benzine, ether, aromatic hydrocarbons and halogenated hydrocarbons. The solubility of fats is associated to their chemical structure. They consists of long, unpolar hydrocarbon chains. WebMay 30, 2024 · Ethanol is an alcohol that is soluble in water. This is because of the hydroxyl group (−OH) in the ethanol that is able to form hydrogen bonds with the water (H2O) molecules.Hydrogen bonding means dipole-dipole interactions between the two molecules and it can be intramolecular and intermolecular.
