Racemization is a process wherein optically active compounds (which consist of only one enantiomer) are converted into an equal mixture of enantiomers with zero optical activity(a racemic mixture). Racemization rates are dependent on the molecule and conditions such as pH and temperature. What is racemisation with example?
WebOct 30, 2014 · Oct 30, 2014 Many diastereomers are optically active, but many are not. Explanation: By definition a diastereomer is any stereoisomer that is not an enantiomer Consider the possible optical isomers of 2,3-dichlorobutane. There are two chiral carbons, so there are 22 = 4 possible optical isomers. However, two of the structures are identical.
