Chapter 21, Problem 21.46P

Interpretation Introduction

(a)

Interpretation:

The structure of carboxylic acid that would produce the given acid chloride when treated with ${\text{SOCl}}_{\text{2}}$ is to be drawn.

Concept introduction:

In the reaction between a carboxylic acid and thionyl chloride to yield an acid chloride. In this reaction the bonds around the $\text{C=O}$ and C-OH are broken and $\text{C=O}$ and C-Cl are formed. Therefore, the original carbon skeleton remains unchanged.
