The products formed in the given set of transformation need to be predicted. Concept introduction: α -bromination of carboxylic acid in presence of bromine and a catalytic amount of phosphorous tribromide to form α -bromocarboxylic acid is known as Hell-Volhard-Zelinsky reaction. The formed α -bromocarboxylic acid when treated with ammonia gives α -aminocarboxylic acid as the product.

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
