Chapter 7.6, Problem 1E

(a)

Interpretation Introduction

Interpretation:

Number of stereo centers in (+)-tartaric acid should be identified.

Concept Introduction :

Stereo centers are those carbon atoms which are attached to 4 different groups. They are also known as chiral centers.

(b)

Interpretation Introduction

Interpretation:

All possible stereo isomers of (+)-tartaric acid should be drawn by indicating the optical activity of the each structure while indicating pairs of them as enantiomers, diastereomers or meso compounds.

Concept Introduction :

Stereoisomers are the compounds which have the same molecular formula but differ only with the partial arrangement of the atoms in the molecule.

(c)

Interpretation Introduction

Interpretation:

Other stereoisomers of (+)-tartaric acid that can be used to resolve racemic 1-phenylethylamine should be identified.

Concept Introduction :

Stereoisomers are the compounds that have the same molecular formula but differ only with the partial arrangement of the atoms in the molecule.

(d)

Interpretation Introduction

Interpretation:

A possible advantage of using a different stereoisomer of (+)-tartaric acid to resolve racemic 1-phenylethylamine should be identified and the reason should be explained.

Concept Introduction :

Stereoisomers are the compounds that have the same molecular formula but differ only with the partial arrangement of the atoms in the molecule.

(e)

Interpretation Introduction

Interpretation:

Importance of the optical purity of the resolving compound should be identified and explained.

Concept Introduction :

Stereoisomers are the compounds which have the same molecular formula but differ only with the partial arrangement of the atoms in the molecule.
