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.
Explanation
Staggered ethane has minimum torsional strain.
Detailed Solution
The magnitude of torsional strain depends on the angle of rotation about the C–C bond axis.
The staggered conformation of ethane is more stable than the eclipsed conformation because the staggered conformation has no torsional strain.
