At room temperature, the eclipsed and the staggered forms of ethane cannot be isolated because

Options

A. both the conformers are equally stable
B. they interconvert rapidly
C. There is a large energy barrier of rotation about the `sigma`-bond
D. the energy difference between the conformers is large.

Answer

B

Explanation

Staggered and eclipsed conformers cannot be physically separated because energy difference between them is so small that they most readily interconvert at room temperature.
