Q. No.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.
