    				| 1. | At room temperature, the eclipsed and the staggered forms of ethane cannot be isolated becauseA. both the conformers are equally stableB. they interconvert rapidlyC. There is a large energy barrier of rotation about the `sigma`-bondD. the energy difference between the conformers is large. | 
| Answer» Correct Answer - B Staggered and eclipsed conformers cannot be physically separated because energy difference between them is so small that they most readily interconvert at room temperature. | |
