β¦ Synopsis
According to the two-stage mechanism of electrophilic aromatic substitution, the halogenation by molecular chlorine and bromine can be formulated by equations ( 1) and ( 2), respectively*.

## Abstract Hydrogen bromide is known to inhibit the bromination of aromatic substrates (ArH), either by fixing up bromine as HBr~3~ or ArH as ArH Β· HBr. However, there is catalysis by HBr in the bromination of mesitylene in acetic acid. The bromination of __o__βxylene in acetic acid in the dark is
rate of intercalation of graphite by bromine has been measured for natural crystals over a range of 500 fold in area and 10 fold in thickness. l'he results have been interpreted in terms of Fick's Law for radial diffusion in a cylinder and a mechanism in which all layers are open to intercalation as
