Question
Chapter 4, Problem 57P
Interpretation Introduction
Interpretation:
The relation between R and S with (+) and (-) has to be explained.
Concept introduction:
The pair of Enantiomers has different configurations (R and S).
Pair of enantiomers has different optical activity, which means if one will show levorotatory, then the other will show dextrorotatory.
The direction and magnitude of rotation of plane-polarized light by an optically compound is measured by using polarimeter.
The specific rotation of enantiomers has equal magnitudes and opposite signs.
