Positive Test Evolution of a carbon dioxide gas is a positive test for the presence of the carboxylic acid and certain phenols The COOH group is the functional group for carboxylic acids. Carboxylic acids are named by replacing –e in the name of the parent alkane with the suffix –oic acid. Upon deprotonation, carboxylic acids yield a carboxylate anion with the general formula R-COO – , which can form a variety of useful salts such as soaps. The preparation of carboxylic acids can be accomplished by the oxidation of a number of functional groups using a wide variety of reagents. These weak acids are widely distributed in nature and are commonly used in consumer products [Figure 25. Selenium Dioxide The functional group is carboxylic acid and compound is butanoic acid, CH 3 CH 2 CH 2 COOH Hope this information will clear your doubts about chemical, structural formula of organic compounds. All members of the carboxylic acid homologous series have the same functional group as ethanoic acid, which is the carboxyl group, -COOH. , the gamma-amine in gamma-aminobutyric acid is on the third carbon of the carbon chain attached to the carboxylic acid group. Coupling Hydrazines, Hydroxylamines and Amines to Carboxylic Acids  As evidenced by functional groups A and B, the same functional group—a carboxylic acid in this case—can serve different roles depending upon its location within  Functional Groups. This type of organic compounds can be obtained by different routes, some  IUPAC nomenclatureEdit. As with aldehydes and ketones, carboxylic acid formulas can be written to show the carbon-to-oxygen double bond explicitly, or the carboxyl group can be Carboxylic acids is a homologous series in which the compounds contain a functional group called the carboxyl group (-COOH). Amoxicillin alone is indicated to treat susceptible bacterial infections of the ear, nose, throat, genitourinary tract, skin, skin structure, and lower respiratory tract.
