SUMMARY
The discussion centers on calculating the enantiomeric excess of a synthetic camphor sample with a specific rotation of -13.9 degrees. Participants emphasize the necessity of knowing the specific rotation of pure R or S camphor to solve the problem accurately. The enantiomeric excess can be determined using the formula: enantiomeric excess = (observed rotation / specific rotation of pure enantiomer) × 100%. The correct answer choices provided include numerical values that suggest varying degrees of enantiomeric excess.
