The correct statement regarding the comparison of staggered and eclipsed conformations of ethane, is (NEET-I 2016)
A.the eclipsed conformation of ethane is more stable
B.the staggered conformation of ethane is more stable✓ Correct
C.the staggered conformation of ethane is less stable
D.the eclipsed conformation of ethane is more stable
Explanation
Magnitude of torsional strain depends upon the angle of rotation about C—C bond. 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.
