Chemistry - GOC Question with Solution | TestHub

(A) the cyclopropenyl cation is aromatic (2π) and the anion is anti-aromatic (4π), so the cation is more stable : correct. (B) the tropylium cation is aromatic (6π) and the anion has 8π, so the cation is more stable : the pair is wrong. (C) the cyclopentadienyl cation is anti-aromatic (4π) and the anion is aromatic (6π), so the cation is less stable : the pair is wrong.
