The correct statement regarding the comparison of staggered and eclipsed conformations of ethane, is:

Option: 1

The staggered conformation of ethane is less stable than eclipsed conformation, because staggered conformation has torsional strain.


Option: 2

The eclipsed conformation of ethane is more stable than staggered conformation, because eclipsed conformation has no torsional strain.


Option: 3

The eclipsed conformation of ethane is more stable than staggered conformation even though the eclipsed conformation has torsional strain.


Option: 4

The staggered conformation of ethane is more stable than eclipsed conformation, because staggered conformation has no torsional strain.

The staggered conformation of ethane is more stable than eclipsed conformation because staggered conformation has no torsional strain.

The magnitude of torsional strain depends upon the angle of rotation about the C-C bond. The staggered form has the least torsional strain and the eclipsed form has the maximum torsional strain. So, the staggered conformation of ethane is more stable than the eclipsed conformation.
