Interpretation:
The direction in which the given mixture will rotate the plane-polarized light is to be determined. The enantiomeric excess of the mixture is to be calculated.
Concept introduction:
The ability of a mixture of enantiomers to rotate the plane polarized light is governed by the percentage of the enantiomer which is in excess. If a given mixture is excess in the (+) enantiomer, then the rotation of the plane polarized light will be in the (+) direction.
If a mixture contains unequal amounts of the (+) and (-) enantiomers, it will be optically active. Such a type of mixture is considered as being a certain percentage racemic, and the remaining percentage is called the enantiomeric excess (ee).

- Nucleophilic Aromatic Substitution: What is the product of the reaction? *see imagearrow_forwardShow the correct sequence to connect the reagent to product. * see imagearrow_forwardThe answer here says that F and K have a singlet and a doublet. The singlet and doublet are referring to the H's 1 carbon away from the carbon attached to the OH. Why don't the H's two carbons away, the ones on the cyclohexane ring, cause more peaks on the signal?arrow_forward
