a) orto-dimetilbenzen + 2Cl2/lumina ->
CH3-C6H4-CH3 + 2Cl2/lumina -> CH3-C6H4-CHCl2 + 2HCl
= clorura de o-metilbenziliden
b) nitrobenzen + HO-NO2 ->
C6H5-NO2 + HO-NO2 -> C6H4(NO2)2 + H2O
= 1,3-dinitrobenzen (m-dinitromenzen)
c) etilbenzen + 2Cl2/AlCl3 ->
C6H5-CH2-CH3 + + 2Cl2/AlCl3 -> amestec de 2 izomeri
Cl-C6H4-CH2-CH3
adica 4-cloroetilbenzen + 2-cloroetilbenzen
sau p-cloroetilbenzen + o-cloroetilbenzen
