SUMMARY
The specific rotation of (R)-(+)-limonene can be lower than the literature value due to the presence of achiral solvents such as methylene chloride, which can dilute the optical activity of the chiral compound. The discussion emphasizes that while ethanol is used as a solvent, the inclusion of methylene chloride can still impact the specific rotation measurement. To accurately calculate specific rotation, one must consider the observed angle of rotation and the concentration of the sample in the polarimeter.
