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 ...
For example, CH 3 −CH(OH)−COOH (lactic acid) is named 2-hydroxypropanoic acid with no "1" stated. Some traditional names for common carboxylic acids (such as acetic acid) are in such widespread use that they are retained in IUPAC nomenclature, [7] though systematic names like ethanoic acid are
When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde , ketone , or carboxylic acid ), then the prefix hydroxy- is used, [ 19 ] e.g., as in 1-hydroxy-2 ...
It is easily prepared in the laboratory by treating sodium metal with absolute ethanol: [3] 2 CH 3 CH 2 OH + 2 Na → 2 CH 3 CH 2 ONa + H 2 The reaction of sodium hydroxide with anhydrous ethanol suffers from incomplete conversion to the ethoxide, but can still produce dry NaOEt by precipitation using acetone, [ 4 ] or by drying using ...
Both industrially and in the laboratory, propionaldehyde has primary application as a chemical building block. [2]: 4 [4] It is predominantly used as a precursor to trimethylolethane (CH 3 C(CH 2 OH) 3) through a condensation reaction with formaldehyde. This triol is an important intermediate in the production of alkyd resins.
It consists of a methylene bridge (−CH 2 − unit) bonded to a hydroxyl group (−OH). This makes the hydroxymethyl group an alcohol . It has the identical chemical formula with the methoxy group ( −O−CH 3 ) that differs only in the attachment site and orientation to the rest of the molecule.
The oxidation products derived from methyl are hydroxymethyl group −CH 2 OH, formyl group −CHO, and carboxyl group −COOH. For example, permanganate often converts a methyl group to a carboxyl (−COOH) group, e.g. the conversion of toluene to benzoic acid. Ultimately oxidation of methyl groups gives protons and carbon dioxide, as seen in ...
1-Hexanol (IUPAC name hexan-1-ol) is an organic alcohol with a six-carbon chain and a condensed structural formula of CH 3 (CH 2) 5 OH. This colorless liquid is slightly soluble in water, but miscible with diethyl ether and ethanol.
