Organic Chemistry Polarimetry question 2. A sample of naproxen (the (S)-enantiomer is the active ingredient in Alleve) was found to havean optical rotation of +45.5°. If the optical rotation of pure (R)-naproxen is -66°, what is the percentenantiomeric excess of the naproxen sample? What percent of the sample is (R) and what percent(S)?

Given data is, Observed optical rotation of (S)-enantiomer=+45.50 Optical rotation of pure…

Answered: 2. A sample of naproxen (the…
