1. alkyl benzene react wity HNO3 (conc. H2SO4, 50°C, reflux)
2. alkylbenzene react with Cl2 (uv)
3. alkyl benzene reacts with Cl2 presence of catalyst AlCl3.
4. toluene (alkylbenzene) + CH3Cl (AlCl3) –> 1,2-dimethylbenzene + 1,4-dimethylbenzene.
5. Toluene + RC=O-Cl (acyl chloride).
6. Toluene react with oxidation agent KMnO4.
7. C6H5-CH2CH3 [O] –> benzoic acid + CO2
8. 1,2-dimethyl benzene [O] –> 1,2-benzenedicarboxylic acid.
9. toluene + CrO2Cl2 –> C6H5-C=O-H (benzaldehyde)

1. alkyl benzene react wity HNO3 (conc. H2SO4, 50°C, reflux –> ortho / para dinitro alkyl benzene.

2. alkylbenzene react with Cl2 (uv) –> C6H5-CH2Cl + Cl2 (uv) –> C6H5-CHCl2 + Cl2 (uv) –> C6H5-CHCl3
C6H5- ini ialah benzene ring yg kita panggil phenyl
Cl hanya tambah pada sidechain -CH3 sahaja
3. alkyl benzene react with Cl2 presence of catalyst AlCl3.
alkyl benzene + Cl2 (AlCl3) –> ortho-chloromethylbenzene + para-chloromethylbenzene.
4. toluene (alkylbenzene) + CH3Cl (AlCl3) –> 1,2-dimethylbenzene + 1,4-dimethylbenzene.

5. Toluene + RC=O-Cl (acyl chloride).
Toluene + CH3C=O-Cl (AlCl3) –> ortho-CH3C=O-toluene + para-CH3C=O-toluene.

6. Toluene react with oxidation agent KMnO4.
Toluene + KMnO4 (H+, reflux) –> benzoic acid.

7. C6H5-CH2CH3 [O] –> benzoic acid + CO2

benzene = C6H6
tapi kalau dia attach pada yang lain, kita tulis C6H5

8. 1,2-dimethyl benzene [O] –> 1,2-benzenedicarboxylic acid.
9. toluene + CrO2Cl2 –> C6H5-C=O-H (benzaldehyde)
