chemical compound / From Wikipedia, the free encyclopedia
For ethanol as a drug or medicine, see Alcohol (drug) and Alcohols (medicine).
Not to be confused with Ethenol or Ethynol.
Ethanol, also known as ethyl alcohol, grain alcohol or just alcohol, is a flammable, colorless chemical compound. Its chemical formula is C2H5OH, also written as C2H6O. It is the active part of alcoholic drinks, which are drunk in most cultures worldwide. It is also used as a solvent because it can dissolve many other chemicals and is not very toxic. Yeast makes most of the ethanol that people use.
