All three orbitals lie in one plane; thus, the cationic centre of the molecule formed by bonding the carbon atom…, The discussion is not yet complete, however. Strictly speaking, Hückel's rules is derived from hydrocarbons, and the generalisation to other compounds is neither straight forward, nor necessary correct. ), carborazine (B Doiron, M.E.
