1)

Benzene + CH3COCOCH3 +AlCl3    > CH3COC6H5      >   m-Bromoacetophenone

                                                             acetobenzene   ( +Br2 )

2) Benzene   >                      Bromobenzene                

                 (Bromination by taking FeBr3 + AlCl3)

Bromobenzrene + HNO3 + H2SO4   >   o-nitro bromo benzene

o-nitro bromobenzene + tert butyl chlorede + Alcl3 > 3-bromo-4-tert butyl nitrobenzene
