Interpretation Introduction

Interpretation: The specific rotation of a mixture of 68% (+)-tartaric acid and 32% ()-tartaric acid is to be calculated on the basis of given information.

Concept introduction: The concentration of the compound affects the rotation of polarized light in Polarimeter. The rotation is also dependent upon the length of the cell and optical activity of the compound. Optical purity of a compound is measured by the enantiomeric excess.

To determine: The specific rotation of a mixture of 68% (+)-tartaric acid and 32% ()-tartaric acid.

Q9 Account for the change in the observed optical rotation of your carvone samples with an increase in concentration of carvone. ☐ At lower concentrations, an increase in the number of ethanol molecules in the sample interferes with the optical rotation reading. ☐ The observed optical rotation of the carvone samples is independent of concentration. ☐ An increase in the number of chiral molecules results in a cumulative effect on the optical rotation.
You synthesize the enantiomer of levetiracetam, but your specific rotation is found to be 67.8. What is the enantiomeric excess (% ee) of this product?
