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.

In his classic studies of stereochemistry and optical activity in organic compounds, Pasteur measured the optical activity of many solutions. For the naturally occurring enantiomer of tartaric acid, [α]D20 = +12.4o (c = 20, H2O). What can be concluded about the ratio of tartaric acid enantiomers present in the solution if the observed rotation is (i) α = -6.0o, or (ii) α =  0o?
