Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....

The carboxylate anion (R−COO − or R−CO − 2) of a carboxylic acid is usually named with the suffix -ate, in keeping with the general pattern of -ic acid and -ate for a conjugate acid and its conjugate base, respectively. For example, the conjugate base of acetic acid is acetate.
The name of the carboxylate anion (R−C(=O)O −) is derived from that of the parent acid by replacing the "–oic acid" ending with "–oate" or "carboxylate." For example, NaC 6 H 5 CO 2, the sodium salt of benzoic acid (C 6 H 5 COOH), is called sodium benzoate. Where an acid has both a systematic and a common name (like CH 3 COOH, for ...
Carboxylate ions are essentially unreactive towards nucleophilic substitution, since they possess no leaving group. The reactivity of these five classes of compounds covers a broad range; the relative reaction rates of acid chlorides and amides differ by a factor of 10 13 .
An oxocarbon anion C x O n− y can be seen as the result of removing all protons from a corresponding acid C x H n O y. Carbonate CO 2− 3, for example, can be seen as the anion of carbonic acid H 2 CO 3. Sometimes the "acid" is actually an alcohol or other species; this is the case, for example, of acetylenediolate C 2 O 2− 2 that would ...
Structure of hydrated nickel acetate. Transition metal carboxylate complexes are coordination complexes with carboxylate (RCO 2 −) ligands. Reflecting the diversity of carboxylic acids, the inventory of metal carboxylates is large. Many are useful commercially, and many have attracted intense scholarly scrutiny.
acetate anion. The acetate anion, [CH 3 COO] −,(or [C 2 H 3 O 2] −) is one of the carboxylate family. It is the conjugate base of acetic acid. Above a pH of 5.5, acetic acid converts to acetate: [1] CH 3 COOH ⇌ CH 3 COO − + H + Many acetate salts are ionic, indicated by their tendency to dissolve well in water.
