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,....
Structure of a carboxylic acid Carboxylate anion 3D structure of a carboxylic acid. In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group.

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 ...
Thus, in cases where two or more canonical forms contribute with equal weight (e.g., in benzene, or a carboxylate anion) and one of the canonical forms is selected arbitrarily, the skeletal formula is understood to depict the true structure, containing equivalent bonds of fractional order, even though the delocalized bonds are depicted as ...
This scheme depicts the general mechanistic steps of HBTU creating an activated ester out of the carboxylate anion of the acid substrate. The deprotination of the carboxylic acid and the aminolysis of the activated ester are not shown. HBTU activates carboxylic acids by forming a stabilized HOBt (Hydroxybenzotriazole) leaving group.
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.
In chemical structure, arachidonic acid is a carboxylic acid with a 20-carbon chain and four cis-double bonds; the first double bond is located at the sixth carbon from the omega end. Some chemistry sources define 'arachidonic acid' to designate any of the eicosatetraenoic acids .
