Question

The diastereomeric pair(s) among the following option(s) is/are 

• A. A
• B. B
• C. C
• D. D

Hint:

Diastereomers differ in their spatial arrangement at one or more stereocenters, unlike enantiomers, which are non-superimposable mirror images.

Answer 1

The Correct Option is A, B, D

Step 1: Understanding diastereomers.
Diastereomers are stereoisomers that are not mirror images of each other and differ in the configuration at one or more stereocenters.
Step 2: Analyzing the options.
- In option (A), the compounds are diastereomers because of the different configurations at their chiral centers.
- In option (B), the compounds are also diastereomers due to the different configurations at the stereocenters.
- In options (C) and (D), the structures do not show sufficient variation in stereochemistry to be diastereomers, as they differ only in substituents without changing the configuration at the chiral centers.
Step 3: Conclusion.
Thus, the diastereomeric pairs are (A) and (B).
