Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a psychoactive drug, best known as the type of alcohol found in alcoholic beverages. While it was a common primary fuel in early liquid-fuel rocket motors, it is widely used as a fuel additive, and is extensively used as a solvent.

Ethanol is a straight-chain alcohol, and its chemical formula is C2H5OH (or CH3-CH2-OH). It has a molecular mass of 46.07 and a normal boiling point of 78.32 °C.

Health effects

Harmful

Heavy drinking can lead to alcoholic hepatitis and may also cause alcohol withdrawal when drinking is stopped.

Drinking can impair performance while intociated[1] and possibly after intoxication[2].

Beneficial

Moderate drinking is associated with reduced cardiac morbidity. Starting moderate drinking during middle age is also associated with cardiovascular benefits and reduced total mortality.[3].[4]
