WebThey are 10^9 times more acidic than even an alkyne H. The reason is that the cyclopentadienide ion (C5H5-) is exceptionally stable because it is aromatic. So it is much easier to lose the sp3 bonded H (the activation energy is much less), and the H is therefore more acidic than you might expect.
