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 ...
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 ...
The name of each substitution is prefixed to the hydride cation name. If many substitutions by the same functional group occur, then the number is indicated by prefixing with "di-", "tri-" as with halogenation. (CH 3) 3 O + is trimethyloxonium. CH 3 F 3 N + is trifluoromethylammonium.
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 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 ...
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 ...
At about 270 Pa of pressure and ambient temperature, the methane ion CH + 4 will react with neutral methane to yield methanium and a methyl radical: [11] CH + 4 + CH 4 → CH + 5 + CH 3 • The methanium ion can also be made in the gas phase via the reaction of methane and an H + ion (i.e. a proton).
