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−CO2H, sometimes as R−C (O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups.

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.

To test this prediction the esterification of acetic acid was compared with that of 2,2-dimethylpropanoic acid, (CH 3) 3 CO 2 H. Here the relatively small methyl group of acetic acid is replaced by a larger tert-butyl group, and the bulkier acid …

Carboxylic acids are organic compounds which incorporate a carboxyl functional group, CO 2 H. The name carboxyl comes from the fact that a carbonyl and a hydroxyl group are attached to the same carbon.

Enter a chemical formula to calculate its molar mass and elemental composition: Molar mass of CH3(CO2H)3 is 150.0868 g/mol

羧基是有机化学中的基本化学基，所有的含有羧基的有机酸物质都可以叫羧酸，由一个碳原子、两个氧原子和一个氢原子组成，化学式-COOH。 如 醋酸 （CH3-COOH）、 氨基酸 都含有羧基，这些羧基与烃基直接连接的化合物，叫作羧酸。
