WebJul 31, 2024 · The term enantiomeric purity (or optical purity) is defined as the fractional excess of one enantiomer over the other. This is expressed in Equation 19-4 in terms of … WebAn enantiomeric excess occurs due to an excess of either enantiomer (R) or enantiomer (S). An enantiomeric excess occurs when there is an excess of either the (R)-enantiomer or the (S)-enantiomer. Optical purity is another term for enantiomeric excess. This is because chiral chemicals are “optically active,” which means they rotate plane ...
In chemistry, an enantiomer – also called optical isomer, antipode, or optical antipode – is one of two stereoisomers that are non-superposable onto their own mirror image. Enantiomers are much like one's right and left hands, when looking at the same face, they cannot be superposed onto each other. No amount of reorientation in three spatial dimensions will allow the four unique g…
