Mechanism for the given transformation need to be drawn and if sodium hydroxide is present in large amount for transesterification. Concept introduction: Transesterification is a process in which the alcohol group present in the carboxylate of triglyceride is exchanged by another organic alcohol group. This can occur in presence of either acid or base as catalyst. The general scheme can be shown as, Please remember that transesterification using basic condition is done in few steps rather than acidic conditions. In presence of excess base the transesterification does not happen instead hydrolysis occurs. To draw : the mechanism for the given transformation.

Question

Look at the following pairs of structures carefully to identify them as representing a) completely different compounds, b) compounds that are structural isomers of each other, c) compounds that are geometric isomers of each other, d) conformers of the same compound (part of structure rotated around a single bond) or e) the same structure.

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.

Concept Introduction:

Hydrolysis is a process in which the ester is converted to its respective carboxylic acid and alcohol in presence of aqueous acid or base. In case of triglyceride the hydrolysis results in formation of glycerol and three fatty acid units. In presence of other organic alcohol unit this hydrolysis occurs if the base is present in large amount rather than transesterification.
