Enantiomeric excess - Massey University

Advanced organic Enantiomeric excess III • Previous slide indicates that a polarimeter measures difference in the amount of each enantiomer • Racemate (racemic mixture) - 1 to 1 mixture of enantiomers (50% of each) • Racemisation - converting 1 enantiomer to a 1:1 mixture of enantiomers • Optical rotation very unreliable so use new methods to measure amounts and use
