1
Q
R&C for nitration
A
conc HNO3, conc H2SO4 catalyst, <55C
- <55 for monosubstituted
- 55-100 for disubstituted
- >100 for trisubstituted
2
Q
R&C for halogenation
A
X2, anhydrous AlX3/FeX3 as catalyst, r.t.
3
Q
R&C for friedel-crafts alkylation
A
RX & excess benzene, anhydrous AlX3/FeX3 as catalyst, r.t.
- excess benzene is to ensure good yield of monosubstituted product
4
Q
R&C for catalytic hydrogenation of benzene
A
H2(g), Ni/Pd/Pt as catalyst, heat
5
Q
R&C for side chain oxidation (methylbenzene)
A
KmnO4 in dilute H2SO4. heat
obs: purple KMnO4 decolourises, white ppt formed
