A structure for atropine (C 17 H 23 NO 3 ) is to be proposed from the following observations: i) On basic hydrolysis atropine yields tropic acid C 6 H 5 CH(CH 2 OH)COOH and tropine (C 8 H 15 NO). ii) Tropine is an optically inactive alcohol that yields tropidene on dehydration with H 2 SO 4 . Concept introduction: Esters when hydrolyzed with bases yield alcohols and carboxylic acids. Alcohols when treated with H 2 SO 4 give alkenes. Symmetrical compounds are optically inactive. To predict: A structure for atropine (C 17 H 23 NO 3 ) from the following observations: i) On basic hydrolysis atropine yields tropic acid C 6 H 5 CH(CH 2 OH)COOH and tropine (C 8 H 15 NO). ii) Tropine is an optically inactive alcohol that yields tropidene on dehydration with H 2 SO 4 . Answer: Structure of atropine is Explanation: Atropine gives tropic acid and an alcohol, tropine when hydrolyzed in the presence of bases. Hence it must be an ester. Tropine upon dehydration gives tropidene. Hence structure of tropine (optically inactive) can be obtained by adding water to the structure of tropidene. The formation of the ester linkage between the OH of atropine and COOH of tropic acid gives atropine. The reactions can be represented as below. Conclusion: Structure of atropine is

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.
