Abstract: In this experiment, the electrophilic aromatic substitution mechanism was used to obtain 4-nitrobromobenzene and 2-nitrobromobenzene. Recrystallization was used to purify 4-nitrobromobenzene.

This is done through an electrophilic attack on the aromatic ring with the help of a carbocation. The Friedel-Crafts alkylation reaction is a method of generating alkyl benzenes by using alkyl halides as reactants. A Lewis acid catalyst such as F e C ...
Webbsponds to the known reactivity of toluene-benzene in nitric acid nitration. On the basis of these results there seems to be 110 reason to suppose that nitronium salt nitration involves a mechan- ism different from that of the nitric acid nitration. INTRODUCTION In recent years the method of competitive rate determination has been extensively PhF was first reported in 1886 by O. Wallach at the University of Bonn, who prepared the compound in two steps. Phenyldiazonium chloride was first converted to a triazene using piperidine: [PhN2]Cl + 2 (CH2)5NH → PhN=N-N(CH2)5 + [(CH2)5NH2]Cl The triazine was then cleaved with hydrofluoric acid: PhN=N-N(CH2)5 + 2 HF → PhF + N2 + [(CH2)5NH2]F
