Cyclopropenyl kation aromat
WebJan 2, 2024 · The cyclopropenyl cation is aromatic because it is meeting all the definitions of Huckel's rule of aromaticity: All carbons are sp2 … With two π electrons, the cyclopropenium cation class obeys Hückel’s rules of aromaticity for 4n + 2 electrons since, in this case, n = 0. Consistent with this prediction, the C3H3 core is planar and the C–C bonds are equivalent. In the case of the cation in [C3(SiMe3)3] SbCl 6, the ring C–C distances range from 1.374(2) to 1.392(2) Å.
