organic synthese help?

Question

synthese following staring at Benzene?

Benzene ring where 1 is NO2 and 4 position is Cl

how you cna obtain this produch if your start from benzene ring.
answer in the back of the book is confusing
its says 1) 2 CH3Cl, AlCl3 ; 2) Br2, FeBr3

IUPAC name is para bromonitrobenzene

Answer 1

Starting with benzene, treat with Cl2 and FeCl3 to make C6H5-Cl. Next, treat with HNO3 + H2SO4 to make a mixture of 2-Cl-C6H4-NO2 (o-chloronitrobenzene) and 4-Cl-C6H4-NO2 (p-chloronitrobenzene, which is is what you want) and separate.

If you treat benzene with CH3Cl and AlCl3, you will get toluene, C6H5-CH3. If you treat that with Br2 + FeBr3, you will get o- and p-bromotoluene.

I think that you have two or three different problems mixed up.
