Chapter 21, Problem 43P
Interpretation Introduction

Interpretation:

The mechanism for interconversion of α-D-glucose and β-D-glucose in dilute HCl is to be drawn.

Concept Introduction:

The hydroxyl group of anomeric carbon in α-D-glucose is protonated by an acid. The lone pair on the ring helps in eliminating a molecule of water which results in the formation of oxocarbenium ion. It is planar molecule. When water approaches from the top of the plane, β-D-glucose is formed.
