2) C6H6+CH3Br=C6H5-CH3+HBr
C6H5-CH3+3HO-NO2=C6H2(NO2)3-CH3+3H2O
2C6H2(NO2)3-CH3+2KMnO4(t)=2C6H2(NO2)3-COOK+2MnO2+3H2O
3)C6H6+CH2=CH2 = C6H5-CH=CH2+H2
C6H5-CH=CH2+Br2=C6H5-CHBr-CH2Br
C6H5-CHBr-CH2Br+2KOH=C6H5-C=-CH+2KBr+2H2O
C6H5-C=-CH+Br2=C6H5-CBr=CHBr
C6H5-CBr=CHBr+KOH=C6H5-C=-CBr+KBr+H2O
4)C6H6+C2H5Cl=C6H5-C2H5+HCl
C6H5-C2H5+Cl2=C6H4Cl-C2H5
C6H4Cl-C2H5+8[O]=C6H4Cl-COOHK+MnO2+2H2O+CO2
