Chapter 24.4, Problem 4P

Interpretation Introduction

Interpretation:

The D, L configuration, the R, S configuration at the chirality center with the highest number of the given aldose are to be determined. The sign of rotation of the aldose is also to be predicted.

Concept introduction:

A carbon atom that has four non-equivalent atoms or groups attached to it is known as a chiral carbon atom (or asymmetric or stereogenic centers).

The naming of a chiral center and geometric isomers are based on Cahn-Ingold-Prelog priority rules.

The D and L configuration are the spatial arrangement of the molecules about the chirality center of the carbohydrates.
