Interpretation Introduction

(a)

Interpretation:

The compound given should be labeled as an aldonic acid or an alditol.

Concept Introduction:

Aldoses can be reduced into alditol using hydrogen gas in the presence of Pd catalyst. Here, carbonyl group of the aldose is converted into a primary alcohol. As well as aldehyde group of an aldose can be oxidized to form a carboxyl group producing an aldonic acid.
