Chapter 22, Problem 4Q

Interpretation Introduction

Interpretation:

The structural formulas of the products (a), (b), (c), and (d) in the given reaction are to be determined.

Concept introduction:

Oxidation of aldoses by nitric acid produces optically inactive aldaric acids. This is due to the formation of meso compounds.

Ruff degradation reaction is used for decreasing the number of carbon atoms of the respective aldoses, thereby, shortening the carbon chain of the compound.

Fischer projection is a way of representing structures of biomolecules using cross formulation of the open chain structures of aldoses such as $\text{D}-\text{Glucose}$.
