Question

What would you conclude about the success of your resolution if the specific rotation of your isolated sample was -20 degree and the literature value for the single (S)-enantiomer is -40 degree? The isolated sample contains an excess (more) of the S-enantiomer relative to the R-enantiomer. The isolated sample contains a 1:1 mixture of R and S enantiomers. The isolated sample contains only the S-enantiomer. The isolated sample contains an excess (more) of the R-enantiomer relative to the S-enantiomer.

Explanation / Answer

Option 1 is the correct answer, the isolated sample will contain more amount of S enantiomer as the specific rotation of sample is also negative.
