WebDec 19, 2024 · Cyclopropenyl is a well-studied system studied. The cation is generated by mixing 3-chlorocyclopropene with strong Lewis acids such as antimony pentachloride, aluminum trichloride, or silver fluoroborate. The salt is stable and can be studied using NMR [1]. The Hückel determinant for the cyclopropenyl cation is shown in the following picture. WebSolution. The correct option is B Cyclopropenyl cation. (a) Cyclopropene is non-aromatic because it does not possess conjugation. (b) Cyclopropenyl cation is aromatic as it follows Huckel's rule 4n+2π electrons, where n =0. (c) Cyclopropenyl anion is anti-aromatic. As it contains 4nπ electrons, where n =1. (d) Cyclobutadiene is anti-aromatic.
