  • Option ii, on the other hand, has a different arrangement of substituents around the chiral center compared to the first structure, but it is not a mirror image of the first structure.
    Therefore, it is a diastereomer of the first structure.
    In conclusion, the answer is b) ii.

  • What are the diastereomers of mannose?

    Diastereomers interact with highly specific sensory receptors.
    For example, d-mannose, a carbohydrate, exists as two diastereomers that differ in the configuration of a hydroxyl group at one center.
    The two isomers are designated α and β.
    The α form tastes sweet, but the β form tastes bitter.
