Ethanol (C2H5OH) gehört zu den linearen n-Alkanolen. Ethanol leitet sich von dem Alkan (gesättigten Kohlenwasserstoff) Ethan (C2H6) ab, in dem formal ein Wasserstoffatom durch die funktionelle Hydroxygruppe (–OH) ersetzt wurde. Zur Benennung wird dem Namen Ethan das Suffix -ol angehängt. Die Summenformel für Ethanol nach dem Hill-System ist C2H6O, die häufig verwendete Schreibweise C2H5OH ist keine Summen-, sondern eine Halbstrukturformel. Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an alcohol with the chemical formula C2H6O. Its formula can also be written as CH3−CH2−OH or C2H5OH (an ethyl group linked to a hydroxyl group). Ethanol is a volatile, flammable, … Skatīt vairāk Ethanol is the systematic name defined by the International Union of Pure and Applied Chemistry for a compound consisting of an alkyl group with two carbon atoms (prefix "eth-"), having a single bond between them (infix "-an … Skatīt vairāk Ethanol is a byproduct of the metabolic process of yeast. As such, ethanol will be present in any yeast habitat. Ethanol can commonly be found in overripe fruit. Ethanol produced by symbiotic yeast can be found in bertam palm blossoms.
