1)Al4C3+12H2O=3CH4+4Al(OH)3

2CH4(t)=C2H2+3H2

C2H2+HOH(t,Hg2+) = CH3-COH

3CH3-COH+2KMnO4=СH3-COOH+2 CH3-COOK+2MnO2+H2O

CH3-COOK+KOH(t)=CH4+K2CO3

2)C2H6+HO-NO2=C2H5-NO2+H2O

C2H5-NO2+3H2=C2H5-NH2+2H2O

C2H5-NH2+HBr=C2H5-NH2*HBr

C2H5-NH2*HBr+NaOH=C2H5-NH2+NaBr+H2O

C2H5-NH2+C2H5-Br=C2H5-NH-C2H5 -р-ция Гофмана.
