Reactions of benzene

Question 1

Halobenzene

Answer 1

benzene reacts with (X2) and FeBr3/AlCl3. Makes substituted benzene and HX.

FeBr makes bromobenzene, where as AlCl3 makes chlorobenzene.

Question 2

Nitration

Answer 2

Benzene reacts with concentrated nitric acid (HNO3) or concentrated sulferic acid (H2SO4), to make a nitrobenzene and H2O.

Nitrobenzene can undergo a reduction to form aminobenzene (dyes)

Question 3

Sulphonation

Answer 3

Benzene reacts with concetrated sulfric acid H2SO4, to form C6H5SO2OH (detergents)

Question 4

Alkylation

Answer 4

Benzene reacts with R-X with aluminium chloride (AlCl3) to form alkylbenzene.
