Question

Which of the following is true for the stereochemical relationship of the given structures (A-D)? 

• (A) and (C) are homomers
• (B) and (C) are enantiomers
• (B) and (D) are homomers
• (A) and (D) are diastereomers

Hint:

Diastereomers are stereoisomers that are not mirror images of each other and are not related by reflection symmetry.

Answer 1

The Correct Option is D

Step 1: Analysis of Stereochemistry.
The structures (A) and (D) are non-mirror image stereoisomers that differ in the spatial arrangement of groups around a chiral center. This makes them diastereomers.

Step 2: Conclusion.
Thus, option (4) is correct, as (A) and (D) are diastereomers, while the other options do not represent accurate stereochemical relationships.

Final Answer: \[ \boxed{\text{(4) (A) and (D) are diastereomers}} \]
