In chemistry, an alcohol (from the Arabic word al-kuḥl, الكحل) is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [2][3] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group strongly modifies ...
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 ...
Alcohol (chemistry), a class of compounds. Ethanol, one of several alcohols, commonly known as alcohol in everyday life. Alcohol (drug), intoxicant found in alcoholic beverages. Alcoholic beverage, an alcoholic drink. Rubbing alcohol, for sanitation and to kill germs.

Ethanol. Butanol. 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 ...
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical compound and the simplest aliphatic alcohol, with the chemical formula C H 3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH).
Amyl alcohols are alcohols with the formula C 5 H 11 OH. [1] Eight are known. A mixture of amyl alcohols (also called amyl alcohol) can be obtained from fusel alcohol. Amyl alcohol is used as a solvent and in esterification, by which is produced amyl acetate and other products. The name amyl alcohol without further specification applies to the ...
Fatty alcohol. Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies with the source. [1][2] Some commercially important fatty alcohols are lauryl ...
