  • Diastereomers are stereoisomers that are not mirror images of each other.

    eg. 1:

    1 and 2 have the same molecular formula and the same structural formula and, therefore, are stereoisomers. 1 and 2 are not mirror images of each other. Thus, they are diastereomers.

    eg. 2:

    3 and 4 have the same molecular formula and the same structural formula and, therefore, are stereoisomers. 3 and 4 are not mirror images of each other. Thus, they are diastereomers.

    eg. 3:

    5 and 6 have the same molecular formula and the same structural formula and, therefore, stereoisomers. 5 and 6 are not mirror images of each other. Thus, they are daiastereomers.

    Cis-Trans isomers are a subset of diastereomers; all cis-trans isomers are diastereomers, but not all diastereomers are cis-trans isomers.
