Question

The two compounds given below are:

• A. Diastereomers
• B. identical
• C. optically inactive
• D. enantiomers

Answer 1

The correct option is D enantiomers

Here, carbon attached to Br is in different alignment so we roatating any one to ${180}^o$ for correct alignment.


The given compound is in Fischer projection. To assign absolute configuration, priority for the group should be given according to their atomic number/mass.

Enantiomers are non-superimposable mirror images.
If two compound have different absolute configuration at respective chiral centre then they are related as enantiomers.
