Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group. The naming of these compounds is governed by IUPAC nomenclature, which ensures systematic and consistent naming of chemicals. Numerous organic compounds have other common names, often originating in historical source material thereof.
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 also used. Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph−COOH) and are named as one of its derivatives ...
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO 2 H, sometimes as R−C(O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups ...
Hexanoic acid CH 3 (CH 2) 4 COOH C6:0 Enanthic acid: Heptanoic acid CH 3 (CH 2) 5 COOH C7:0 Caprylic acid: Octanoic acid CH 3 (CH 2) 6 COOH C8:0 Pelargonic acid: Nonanoic acid CH 3 (CH 2) 7 COOH C9:0 Capric acid: Decanoic acid CH 3 (CH 2) 8 COOH C10:0 Undecylic acid: Undecanoic acid CH 3 (CH 2) 9 COOH C11:0 Lauric acid: Dodecanoic acid CH 3 (CH ...
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
The Geneva Nomenclature of 1892 was created as a result of many other meetings in the past, the first of which was established in 1860 by August Kekulé. Another entity called the International Association of Chemical Societies (IACS) existed, and on 1911, gave vital propositions the new one should address: [2]
The locant is incorporated into the name of the molecule to remove ambiguity. Thus the molecule is named either pentan-2-one or pentan-3-one , depending on the position of the oxygen atom. Any side chains can be present in the place of oxygen and it can be defined as simply the number on the carbon to which any thing other than a hydrogen is ...
In organic chemistry, a ketene is an organic compound of the form RR'C=C=O, where R and R' are two arbitrary monovalent chemical groups (or two separate substitution sites in the same molecule). [1] The name may also refer to the specific compound ethenone H 2 C=C=O, the simplest ketene. [2] Although they are highly useful, most ketenes are ...
