Cyclopentadiene is much more acidic than cyclopentane, beacuse -
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.
