Question
Chapter 7.6, Problem 8E
Interpretation Introduction
Interpretation:
This needs to be explained that if one stereocenter of the (+)-tartaric acid has R configuration then the configuration of the other stereocenter is also R.
Concept Introduction :
The stereo isomers having different configuration at all stereocenters are known as enantiomers of each other and if there is different configuration at only one stereocenter but same at other and both isomers are non-mirror image of each other, they will be diastereomers.
