Alcohol (simple structure: CH3CH2OH) is a kind of alcohol, is the main component of wine, it is also known as alcohol, in some places commonly known as the fire wine. The chemical formula can also be written as C2H5OH or EtOH, Et represents ethyl. Ethanol is a flammable, commonly used fuel, solvent and is also used to make other compounds. Industrial alcohol contains a small amount of methanol. alcohol mainly refers to ethanol with a concentration of about 75%, and also includes other concentrations of alcohol widely used. Ethanol and methyl ether are isomers.

Bidhaa hii ni nini?
Ethanol is an organic compound. Its structural formula is CH3CH2OH or C2H5OH, and its molecular formula is c2h6o, commonly known as alcohol.
Under normal temperature and pressure, ethanol is a kind of volatile colorless transparent liquid with low toxicity. Pure liquid cannot be drunk directly. The aqueous solution of ethanol has the smell of wine aroma, slightly irritating and sweet. Ethanol is flammable, and its vapor can form an explosive mixture with air. Ethanol can be miscible with water in any ratio, chloroform, ether, methanol, acetone and most other organic solvents.
