Final answer:
Conformers can be separated despite having negligibly small differences in potential energy. The correct option is (C).
Step-by-step explanation:
The correct answer is C. Assertion is correct but Reason is incorrect.
Conformers are stereoisomers that can be interconverted by rotations around single bonds. They have slightly different potential energy due to different spatial arrangements of atoms.
Although conformers have small differences in potential energy, it is still possible to separate them. Separation methods such as chromatography and distillation can be used to separate conformers based on their physical properties, such as boiling points or solubilities.
Therefore, while the Assertion is correct and conformers may have negligibly small differences in potential energy, the Reason is incorrect as conformers can indeed be separated.
