Question
Chapter 17, Problem 3Q
Interpretation Introduction
Interpretation:
The eight stereocentres in each of the two nitrogen heterocyclic compounds should be identified.
Concept introduction:
Optical activity is the ability of substances to rotate plane-polarized light when it falls on it.
A molecule is called chiral if it possesses no plane of symmetry and is not superimposable on its mirror image. A molecule that has a tetrahedral atom with four different substituents known as stereocenter is chiral. A stereocenter is also called a chiral or asymmetric center. Chiral compounds exhibit the property of enantiomerism. Enantiomers are stereoisomers that have non-superimposable mirror images.
