Questions and Answers

Is (S)-carvone levorotatory or dextrorotatory?

  • Dextrorotatory (correct)
  • Both levorotatory and dextrorotatory
  • Levorotatory
  • Neither levorotatory nor dextrorotatory
  • Which enantiomer is in excess in the mixture?

  • Both are present in equal amounts

    Study Notes

    Optical Activity of (S)-Carvone

    • The specific rotation of pure (S)-carvone is +61°
    • A solution of (S)- and (R)-carvone has a specific rotation of −23°

    Chiral Properties

    • (S)-carvone is dextrorotatory
    • The mixture is not racemic

    Calculation of Excess Enantiomer

    • Calculation of the percentage of each enantiomer requires further calculation. The provided information is insufficient to proceed with this.
