Ethanol, also called alcohol, ethyl alcohol, and drinking alcohol, is a compound and simple alcohol with the chemical formula . Its formula can be written also as −− or − (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor. It is used as a drug and is the principal type of alcohol found in alcoholic drinks. 

Ethanol is naturally produced by the fermentation of sugars by yeasts or via petrochemical processes, and is most commonly considered as a popular recreational drug. It also has medical applications as an antiseptic and disinfectant. The compound is widely used as a chemical solvent, either for scientific chemical testing or in synthesis of other organic compounds, and is a vital substance utilized across many different kinds of manufacturing industries. Ethanol is also used as a clean energy burning fuel source. 

"Ethanol" is the systematic name defined by the International Union of Pure and Applied Chemistry (IUPAC) for a compound consisting of alkyl group with two carbon atoms (prefix "eth-"), having a single bond between them (infix "-an-"), attached functional group-OH group (suffix "-ol"). 

The "eth-" prefix and the qualifier "ethyl" in "ethyl alcohol" originally come from the name "ethyl" assigned in 1834 to the group - by Justus Liebig. He coined the word from the German name "Aether" of the compound -O- (commonly called "ether" in English, more specifically called "diethyl ether"). According to the Oxford English Dictionary, "Ethyl" is a contraction of the Ancient Greek αἰθήρ (aithḗr, “upper air”) and the Greek word "" ("hyle", substance). QUESTIONS:
