    Identify the correct statement about the following pairs of compounds.

    A) A and B diastereomers; C and D diastereomers

    B) A and B enantiomers ; C and D diastereomers

    C) A and B diastereomers ; C and D enantiomers

    D) A and B enantiomers ; C and D enantiomers

    Correct Answer: D

    Solution :

    Diastereomers are the optically active isomers in which the mirror images are non-superimpossable on each other whereas enantiomers are those optical isomers in which the mirror images are superimposable on each other.
    Because A and B are non-superimposable mirror images of each other.
    Hence, these are diastereomers.
    Both C and D are the superimposable mirror images of each other hence, are enantiomers.
