Question:

Cyclopentadiene and cycloheptatriene are both treated with n-BuLi (n-butyl lithium), a strong base. Determine which compound is more acidic, and provide an explanation.

Answer:

Cyclopentadiene is more acidic than cycloheptatriene because the conjugate base of cyclopentadiene fulfills Huckel's rules (6 pi electrons), thus making it aromatic. The conjugate base of cycloheptatriene affords an anti-aromatic species (8 pi electrons), which is very unstable.
