Question

An enantiomeric mixture of compounds A and B together react with a reagent R to give two new products, compound C from enantiomer A, and compound D from enantiomer B. The reaction coordinate diagram below describes the energetics for this process; note that each enantiomer A and B has its own reaction coordinate (A is the solid line, and B is the dashed line). Are the two distinct transition states (TS's) enantiomeric or diastereomeric? Is the reagent R achiral or chiral? TS's R enantiomeric chiral (one enantiomer) enantiomeric achiral diastereomeric chiral (one enantiomer) diastereomeric achiral

Explanation / Answer

a) enantiomeric chiral (one enantiomer)
