In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [ 3 ] [ 4 ] Alcohols range from the simple, like methanol and ethanol , to complex, like sugar alcohols and cholesterol .
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
A primary alcohol is an alcohol in which the hydroxy group is bonded to a primary carbon atom. It can also be defined as a molecule containing a “–CH 2 OH” group. [ 1 ] In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR 2 OH”, where “R” indicates a carbon-containing group.
Sugar alcohols can be, and often are, produced from renewable resources.Particular feedstocks are starch, cellulose and hemicellulose; the main conversion technologies use H 2 as the reagent: hydrogenolysis, i.e. the cleavage of C−O single bonds, converting polymers to smaller molecules, and hydrogenation of C=O double bonds, converting sugars to sugar alcohols.

Alcohol has been produced and consumed by humans for its psychoactive effects since c. 7000–6600 BC. [21] Alcohol is the second most consumed psychoactive drug globally, behind caffeine. [22] [23] Drinking alcohol is generally socially acceptable and is legal in most countries, unlike with many other recreational substances.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Vodka, gin, baijiu, shōchū, soju, tequila, rum, whisky, brandy, and singani are examples of distilled drinks. Beer, wine, cider, sake, and huangjiu are examples of fermented drinks. Hard liquor is used in North America, and India, to distinguish distilled drinks from undistilled ones, and to suggest that undistilled are implicitly weaker.
