WebA substance that is a single, pure enantiomer (i.e., has 100% ee) is called homo chiral or optically pure. The product of this reaction, one possible step in the manufacture of naproxen (an analgesic ), is a mixture of 90% S … WebSo we have 100% optical purity, so this is an optically pure solution. For part B, let's do this for a solution that contains equal amounts of both enantiomers. So when that happens, it's called a racemic mixture. So if we have equal amounts of both, that must mean we have 50% of one enantiomer, and 50% of the other.
