In chemistry, an alcohol is any organic compound in which a hydroxyl group (-OH) is bounce to a carbon atom of an alkyl or substitute alkyl set. The universal formula for a easy acyclic alcohol is CnH2n+1OH.
The word alcohol was introduced into the English language circa 1543 from the Arabic. In layman's terms, it usually refers to ethanol, also recognized as grain alcohol or (older) spirits of wine, or to any alcoholic drink. Ethanol is a neutral, volatile liquid with a mild odor which can be obtain by the fermentation of sugars. Ethanol is the most widely use depressant in the world, and has been for thousands of years. This sense underlies the term alcoholism.
Other alcohols are usually described with a descriptive adjective, as in isopropyl alcohol or wood alcohol. The suffix -ol appear in the "official" IUPAC chemical name of all alcohols.
There are three major subsets of alcohols: primary (1°), secondary (2°) and tertiary (3°), base upon the amount of carbon atoms the C-OH group's carbon is bond to. Ethanol is a simple 'primary' alcohol. The simplest minor alcohol is isopropyl alcohol (propan-2-ol), and a simple tertiary alcohol is tert-butyl alcohol.
