Chapter 20, Problem 20.24P

Interpretation Introduction

Interpretation:

If the hydroxyl groups on carbons 1, 2, 3 and 4 of a-D-glucose are at equatorial positions or not should be explained.

Concept Introduction:

To verify if the hydroxyl groups on carbons 1, 2, 3 and 4 of a-glucose are equatorial let us first understand the axial and equatorial positions.

In the chair conformations, axial bonds are parallel to the axis of the ring while equatorial bonds are perpendicular to the axis of the ring.
