Ethanol

Ethanol, also called ethyl alcohol, grain alcohol, or drinking alcohol, is a flammable, colorless, chemical compound. It is best known as the type of alcohol found in alcoholic beverages and in thermometers. In common usage, it is often referred to simply as alcohol.

Ethanol is also known as EtOH, using the common organic chemistry notation of representing the ethyl group (C2H5) with Et.

Ethanol is a straight-chain alcohol, and its molecular formula is C2H5OH. An alternative notation is CH3-CH2-OH, which indicates that the carbon 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).

Its empirical formula is C2H6O, a formula that it shares with dimethyl ether.

Ethanol is used in UNSC commercial vehicles as a biofuel, notably more advanced variants of the JOTUN series of agricultural drones. It is likely that this was Corn Ethanol, a derivative of corn used as an alternative fuel.
