Question

You are given a solution containing a pair of enantiomers (a and b). careful measurements show that the solution contains 77% a and 23%
b. what is the ee of this solution?

Answer 1

The ee solution would be 55%

Answer 2

Answer:

54%

Explanation:

Enantiomers are molecules with the same molecular formula that are images that can't be overlapping. The chiral carbon is a carbon atom that has four different bonds.

The pure enantiomer can deviate the light, and the mixture of them will do that, but the angle of deviation depends on the enantiomer in excess (ee). Ee % is the % of the enantiomer in excess less than the other.

In this case, because a > b, a is excess, so:

ee = 77% - 23%

ee = 54%
