Chapter 24.18, Problem 24P

Interpretation Introduction

Interpretation:

The hexose that gives the same aldaric acid on oxidation as given by $\text{D-glucose}$ is to be identified.

Concept introduction:

The oxidation of both groups ${\text{CH}}_{\text{2}}\text{OH}$ and $\text{CHO}$ of aldoses to carboxylic group forms an aldaric acid.

As both the groups are $\text{COOH}$ in aldaric acid, the numbering of carbon can start from either of $\text{COOH}$ group.
