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 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 a torsional strain. |
