Vedclass · Answer

(B) Stability is determined by aromaticity,resonance,and inductive effects.$(i)$ Cyclopropenyl cation is aromatic ($2\pi$ electrons),while cyclopropenyl anion is anti-aromatic ($4\pi$ electrons). Thus,the first is more stable.$(ii)$ Cyclopentadienyl cation is anti-aromatic ($4\pi$ electrons),while cyclopentadienyl anion is aromatic ($6\pi$ electrons). Thus,the second is more stable.$(iii)$ Cycloheptatrienyl cation is aromatic ($6\pi$ electrons),while cycloheptatrienyl anion is anti-aromatic ($8\pi$ electrons). Thus,the first is more stable.$(iv)$ The carbocation with the $-OH$ group is stabilized by resonance (lone pair donation),whereas the carbocation with the $-CH_3$ group is stabilized only by hyperconjugation and inductive effect. Thus,the first is more stable.Therefore,only in pair $(ii)$ is the second ion more stable than the first.

In which pair is the second ion more stable than the first?
