The complete and detailed mechanism for the acid-catalyzed ester hydrolysis in Equation 21-30 is to be drawn. Concept introduction: The ester is hydrolyzed to the carboxylic acid under acidic conditions, so no strong base should appear in the mechanism. Water is the nucleophile, and the leaving group is a molecule of ethanol. Proton transfer steps are incorporated to avoid the appearance of strong bases.

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.

2. Provide a clear arrow-pushing mechanism for the following reactions. Do not skip proton transfers, do not combine steps, and make sure your arrows are clear enough to be interpreted without ambiguity. a. CH3 Ph OEt هد Ph CH3 Hint: the species on the left is an ynolate, which behaves a lot like an enolate.

b. CH3 H3C CH3 CH3 H3C an unexpected product, containing a single 9- membered ring the expected product, containing two fused rings H3C-I (H3C)2CuLi an enolate
