Chapter 3, Problem 51DSP

Interpretation Introduction

Interpretation:

The $\text{β-furanose}$ form of D-xylose is to be identified.

Concept introduction:

Compared to the $\text{β-pyranose}$ form of D-ribose, all the $\text{OH}$ groups in D-xylose are equatorial.

From this, the structure of the $\text{β-pyranose}$ form of D-xylose can be drawn.

By analogy, the structure of the $\text{β-furanose}$ form of D-xylose can be drawn, changing the position of the $\text{OH}$ groups as required.
