Abstract

Abstract Tetraphenyl-p-xylene-glycol, tetraphenyl-phthalein and Dipheno(3-10′)thiazinyl are shown to form dipositive carbonium ions, but triphenyl acetic acid, 2-3-5-6 tetramethyl benzoic acid, 2-3-4-5-6 pentamethyl benzoic acid, tert-butyl alcohol, triphenyl carbinol, tri-p-tolyl carbinol, tri-o-tolyl carbinol, tri-p-chlorophenyl carbinol and tri-p-nitrophenyl carbinol form monopositive carbonium ions in chlorosulphuric acid, as revealed by conductometric and u.v. spectral studies. Oxalyl chloride decomposes while ethylene glycol is sulphonated in chlorosulphuric acid. Dichloroethane behaves as a non-electrolyte but dibromomethane disproportionates in this medium.
