Question
Chapter 20, Problem 40P
Interpretation Introduction
Interpretation:
The product obtained from the reaction of D-ribose with one equivalent of methanol and HCl is to be predicted.
Concept Introduction:
The hydroxyl group of anomeric carbon 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 the alcohol approaches from the top of the plane, the β-glycoside is formed. When the alcohol approaches from the bottom of plane, the α-glycoside is formed.
