Unverified50% confidenceFactExact time
Enantiomeric excess (ee value) is used to quantitatively describe the degree of excess of one enantiomer relative to the other in a product; the "from 50:50 to 51:49" observed by Kogan corresponds to an ee value of about 2%.

UnverifiedEnantiomeric excess (ee value) is defined as the ratio of the difference between the concentrations of the two enantiomers to their sum, expressed as a percentage.80% similarUnverifiedEnantiomeric excess (ee value): ee = 100% means the reaction produces only one enantiomer, while ee = 0% means the two enantiomers are present in equal amounts (a racemic mixture).69% similarUnverifiedIn the Elo rating system, when the score difference between two models is within 30–50 points, they are generally considered to be at a statistically indistinguishable level.65% similarUnverifiedEnantiomeric excess (ee) is the standard measure of chiral purity; if a product contains 90% right-handed and 10% left-handed forms, then ee = 80%.61% similar
