Chapter 24, Problem 45DSP

Interpretation Introduction

Interpretation:

The two possible structures for $\text{(-)-arabinose}$ are to be chosen.

Concept introduction:

Aldoses and ketoses can be oxidized using nitric acid.

Upon oxidation, both the carbon atoms at the end are oxidized to $\text{COOH}$ group.

A chiral compound having at least one carbon atom which is linked to four different atoms or groups.

A chiral compound does not have any elements of symmetry.

Molecules containing two identical chiral centers can be achiral.

A molecule containing two or more equivalent chiral centers and an internal plane of symmetry or a center of symmetry is called a meso isomer or compound.

Meso compounds are optically inactive.
