Diastereomers are stereoisomers that are not mirror images of each other and have different physical and chemical properties. JEE preparation requires clarity of concepts in Diastereomers. Click here to access solved previous year questions, solved examples and important formulas based on the chapter. Learn what diastereomers are, how they differ from enantiomers and geometrical isomers, and how to identify and separate them. See examples of diastereomers with two or more stereocenters and their physical and chemical properties. Note carefully the difference between enantiomers and diastereomers: enantiomers have opposite configurations at all chirality centers, whereas diastereomers have opposite configurations at some (one or more) chirality centers but the same configuration at others. A full description of the four stereoisomers of threonine is given in Table 5.2.
