Optically pure meaning

WebA sample of a pure chiral compound uncontaminated by its enantiomer is said to be enan-tiomerically pure. (The term optically pure is sometimes used to mean the same thing.) In a mixture of the two enantiomers, each contributes to the optical rotation in proportion to its concentration, as Eq. 6.1 shows. 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.
