Chapter 19, Problem 26P

Interpretation Introduction

Interpretation:

The final product with a molecular formula ${\text{C}}_{\text{9}}{\text{H}}_{\text{9}}{\text{ClO}}_{\text{3}}$ for the given series of reaction is to be stated.

Concept introduction:

Thionyl chloride $\left({\text{SOCl}}_{\text{2}}\right)$ can be used to convert carboxylic into acyl chloride. The overall reaction converts poor leaving group, $\text{OH}$, into a good leaving group, $\text{Cl}$.

Lithium aluminum hydride is a strong reducing agent. The reduction of a carboxylic acid by ${\text{LiAlH}}_{\text{4}}$ yields alcohol.

Oxidation reaction involves an increase in the $\text{C}-\text{X}$ bonds (where $\text{X}$ usually is oxygen or a halogen atom) or decrease in the $\text{C}-\text{H}$ bonds.

Reduction reaction involves a decrease in the $\text{C}-\text{X}$ bonds (where $\text{X}$ usually is oxygen or a halogen atom) or increase in the $\text{C}-\text{H}$ bonds.
