Chemistry - GOC Question with Solution | TestHub

(A) deprotonating cyclopentadiene gives the aromatic cyclopentadienyl anion (6π), while benzene would give an unstabilised aryl anion : correct. (B) cycloheptatriene gives an anti-aromatic 8π anion but still has an $s{p}^3$ C-H that is far more acidic than any vinylic C-H of cyclooctatetraene, so the order shown is wrong. (C) cyclopropene gives the anti-aromatic cyclopropenyl anion (4π), so cyclopentadiene is more readily deprotonated : correct. Correct pairs : A and C.
