AIIMS 2014 Chemistry Conformational Isomerism MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Assertion Conformers are impractical to separate. Reason Conformers have negligibly small difference in their potential energy.

A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

B

Both Assertion and Reason are true and Reason is not the correct explanation of Assertion

C

Assertion is true but Reason is false

D

Both Assertion and Reason are false

Correct Answer

Option A

Detailed Explanation

The correct answer is A because both the assertion and the reason are true: conformers, which are different spatial arrangements of the same molecule, cannot be easily separated due to their rapid interconversion and the negligible energy differences between them. The reason correctly explains why this is the case, as the small differences in potential energy mean that conformers exist in a dynamic equilibrium, making separation impractical.
