Ethanol, also called ethyl alcohol, pure al-
cohol, 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 and in
modern thermometers. Ethanol is one of the
oldest recreational drugs. In common usage,
it is often referred to simply as alcohol or
spirits.
Ethanol is a straight-chain alcohol, and its
molecular formula is C2H5OH. Its empirical
formula is C2H6O. An alternative notation is
CH3-CH2-OH, which indicates that the car-
bon of a methyl group (CH3-) is attached to
the carbon of a methylene group (-CH2-),

which is attached to the oxygen of a hydroxyl
group (-OH). It is a constitutional isomer of
dimethyl ether. Ethanol is often abbreviated
as EtOH, using the common organic chem-
istry notation of representing the ethyl group
(C2H5) with Et.
