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

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:

Mechanism for the given transformation need to be drawn and if sodium hydroxide is present in large amount for transesterification.

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.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule
