Concept explainers
(a)
Interpretation: The structure of the enantiomers of the MSG needs to be drawn.
Concept Introduction: When four different groups are attached to single atom that atom is called chiral atom. Enantiomers have the same molecular formula but the special arrangements of the atom are differ.
(b)
Interpretation: The optical purity and percentage of the R and S enantiomers needs to be determined.
Concept Introduction: The optical purity of the solution is the ratio of the observed specific rotation to the specific rotation of pure solution.
(c)
Interpretation: The optical purity and percentage of the enantiomers of the solution needs to be determined.
Concept Introduction: Optical purity is the ratio of observed rotation to the specific rotation of pure solution.
