Chapter 5, Problem 5.68P

Interpretation Introduction

Interpretation:

It is to be explained how the results of specific reactions carried out on $\text{D-glucose}$ and $\text{D-mannose}$ agree with the currently known structures of the two sugars. The type of sugar that was produced when $\text{D-glucose}$ was reacted should also be determined.

Concept introduction:

A chiral compound contains at least one carbon which is bonded to four different atoms or groups. D-sugar is one in which the $\text{OH}$ group, attached to the highest numbered chirality center, is present on the right side of the vertical chain in Fischer projection. During a rotation of ${180}^0$ in the plane of paper for the Fischer projection, the groups which are on the right side switch places with the groups which are on the left side.
