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.

Cyclopentadiene is much more acidic than cyclopentane, because:

1. Cyclopentadiene has conjugated double bonds.
2. Cyclopentadiene has both sp2 and sp3 hybridized carbon atoms.
3. Cyclopentadiene is a strain-free cyclic system.
4. Cyclopentadienyl anion ion, the conjugate base of cyclopentadiene, is an aromatic species and hence has higher stability.
