MSISTRY 203-204 Grganic Chemistry Lab Manual 3 4 EXPERIMENT #9 The Preparation of t Butyl Chloride A tertiary carbonium ion is more rapidly formed than a secondary or primary carbonium ion. Once formed, a tertiary carbonium ion is stabilized by charge dispersal to a greater extent than a secondary or primary carbonium ion. It therefore has a longer life expectancy. Primary carbonium ions, protons, may exist in solution only in solvated form have any free existence, they dehydration reaction and...
