Question:
Which are the correct definitions:
A. Enantiomer: Nonsuperimposable mirror images
B. Isomer: Nonsuperimposable structure
C. Configuration: Arrangement of atom that characterises a particular stereoisomer
D. Diastereomer: Stereoisomers that are mirror image of each other
Which are the correct definitions:
A. Enantiomer: Nonsuperimposable mirror images
B. Isomer: Nonsuperimposable structure
C. Configuration: Arrangement of atom that characterises a particular stereoisomer
D. Diastereomer: Stereoisomers that are mirror image of each other
Show Hint
Enantiomers = Mirror. Diastereomers = NOT Mirror.

- A, B, C Only
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
This covers the fundamental terminology of stereochemistry.
Step 2: Meaning
Stereoisomers differ in the spatial arrangement of atoms.
Step 3: Analysis
A is correct; enantiomers are mirror images. B is correct in a broad sense; isomers have different structures. C is correct; configuration defines the spatial layout. D is incorrect because diastereomers are stereoisomers that are NOT mirror images of each other.
Step 4: Conclusion
Definitions A, B, and C are accurate as stated.
Final Answer: (D)
