WebWhat is the enantiomeric excess of a sample of limonene that has a specific rotation of -38°, given that the specific rotation of (S)-limonene is -116°? What is the percentage of the R enantiomer in this solution? [8 points] This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebThe observed rotation of the mixture is levorotary (negative, counter-clockwise), and the specific rotation of the pure S enantiomer is given as dextrorotary (positive, clockwise), meaning that the pure R enantiomer must be levorotary, and the mixture must contain more of the R enantiomer than of the S enantiomer.
