Question
Chapter 28, Problem 28.8P
Interpretation Introduction
Interpretation: Two possible epimers of D-erythrose are to be drawn and their name is to be stated.
Concept introduction: Two compounds which are neither superimposable nor mirror images to each other and the configuration of one of their stereogenic centers is different are known as epimers.
