Chapter 20, Problem 20.53AP

Interpretation Introduction

(a)

Interpretation:

The curved-arrow mechanism for the given decarboxylation reaction is to be stated.

Concept introduction:

The term decarboxylation means the loss of a carbon dioxide molecule. The decarboxylation of carboxylic acids leads to the formation of alkane. The decarboxylation of the carboxylic acid can be done by heating it in acidic solution.

Interpretation Introduction

(b)

Interpretation:

An explanation as to why neither very low $\text{pH}$ nor very high $\text{pH}$ is suitable for the decarboxylation of the given reaction is to be stated.

Concept introduction:

The term decarboxylation means the loss of a carbon dioxide molecule. The decarboxylation of carboxylic acids leads to the formation of alkane. The decarboxylation of the carboxylic acid can be done on heating in acidic solution.

Interpretation Introduction

(c)

Interpretation:

An explanation as to how the primary amines catalyze the decarboxylation of acetoacetic acid is to be stated.

Concept introduction:

The term decarboxylation means the loss of a carbon dioxide molecule. The decarboxylation of carboxylic acids leads to the formation of alkane. The decarboxylation of the carboxylic acid can be done on heating in acidic solution.
