The problem statement should be checked to ascertain which of these compounds is meant because they give different …
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. WebThe cyclopropenyl anion 1a has 4 π-electrons and should be antiaromatic. Kass has provided computational results that strongly indicate it is not antiaromatic! 1. Let’s first …
WebOct 31, 2024 · Coming back to your original question: What is the reason for the exceptional stability of tricyclopropyl-cyclopropenyl carbocation? In extremely simple terms, it's exceptional stable because of the cyclopropenium core structure, because it is aromatic. Larger substituent moieties usually further stabilise such substructures, because they … WebTropylium cation. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). In organic chemistry, the tropylium ion or cycloheptatrienyl cation is an aromatic species with a formula of [C 7 H 7] +.
