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

A $The eclipsed conformation of ethane is more stable than staggered conformation, because eclipsed conformation has no torsional strain.$
B $The eclipsed conformation of ethane is more stable than staggered conformation even though the eclipsed conformation has torsional strain.$
C $The staggered conformation of ethane is more stable than eclipsed conformation, because staggered conformation has no torsional strain.$
D $The staggered conformation of ethane is less stable than eclipsed conformation, because staggered conformation has torsional strain.$

Solution & Step-by-step Explanation

In the staggered conformation of ethane, the hydrogen atoms on adjacent carbons are as far apart as possible, minimizing electron-cloud repulsion. This means it has minimum torsional strain. In the eclipsed conformation, the hydrogen atoms are aligned, leading to maximum torsional strain and higher energy (less stability).

Try it yourself before checking the explanation above.

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

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

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

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

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