Which of the following statements is true regarding the conformers of ethane?
| 1. | Bond angle remains the same but bond length changes. |
| 2. | Bond angle changes but bond length remains the same. |
| 3. | Both bond angle and bond length change. |
| 4. | Both bond angle and bond length remain the same. |
The correct statement regarding the comparison of staggered and eclipsed conformations of ethane is:
| 1. | The eclipsed conformation of ethane is more stable than staggered conformation because eclipsed conformation has no torsional strain |
| 2. | The eclipsed conformation of ethane is more stable than staggered conformation even though the eclipsed conformation has a torsional strain |
| 3. | The staggered conformation of ethane is more stable than the eclipsed conformation because staggered conformation has no torsional strain |
| 4. | The staggered conformation of ethane is less stable than eclipsed conformation because staggered conformation has torsional strain |
