The O-H-peaks due to carboxylic acids (example 6) show a very broad and less intense peak between 2500 and 3500 cm-1. The change in peak shape is a result of the different degree of hydrogen bonds in alcohol and carboxylic acids. These … WebThe carboxyl group, often written as COOH or CO H, gives the carboxylic acid its acidic character. As with any Bronsted acid, a carboxylic acid reacts with hydroxide ion to produce the conjugate base of the acid, the carboxylate ion and water as a byproduct. The resulting carboxylate ion is water soluble and insoluble in organic solvents.

WebA carboxylic acid first adds to the DCC molecule to form a good leaving group, which can then be displaced by an amine during nucleophilic substitution to form the corresponding amide. The reaction steps are shown below: Step 1: Deprotonation of the acid. Step 2: Nucleophilic attack by the carboxylate. Step 3: Nucleophilic attack by the amine.
