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.

1. Toluene

2. Aniline

3. Benzene

4. Isopropyl benzene
