Chapter 3, Problem 52DSP

Interpretation Introduction

Interpretation:

The most stable pyranose conformation of the given carbohydrate is to be identified.

Concept introduction:

In the structure of planar cyclohexane, the substituents that are on the wedge bonds must be above the plane of the ring in the chair form.

The substituents that are on the dash bond in the planar cyclohexane must be below the plane of the ring in the chair form.

The most stable conformation of a cycloalkane is the one in which most of the substituents occupy equatorial orientation.
