Question

Chimie organica, arene am si eu nevoie de ajutor:


a) orto-dimetilbenzen + 2Cl/lumina ->

b) nitrobenzen + HO-NO2 ->

c) etilbenzen + 2Cl2/AlCl3 ->

Answer 1

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
