The reaction of methyl o-bromobenzoate with aqueous acid and heat has to be given. Concept Introduction: Hydrolysis of Ester: The reaction in which a bond is broken by the addition of water molecule is called as hydrolysis. Acid hydrolysis of ester: Hydrolysis of esters yields the carboxylic acid and an alcohol. The heat is required to initiate the reaction and a small amount of acid (H + ) is added as catalyst. The general reaction of ester hydrolysis is shown below,

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.

Interpretation Introduction

Interpretation:

The reaction of methyl o-bromobenzoate with aqueous base and heat has to be given.

Concept Introduction:

Hydrolysis of Ester:

The reaction in which a bond is broken by the addition of water molecule is called as hydrolysis.

Base hydrolysis of ester:

Hydrolysis of an ester could also be catalyzed by the presence of a strong base. The base-catalyzed hydrolysis of an ester is called as saponification.

The general reaction of base-catalyzed hydrolysis is shown below,

In case of base-catalyzed hydrolysis of an ester, the carboxylic acid does not exist. The reaction results in the formation of salt of carboxylic acid containing the cation of the base catalyst.
