Question

1)Al4C3(+H2O)=>X1(t)=>X2=> этаналь (KMnO4+H2O)=>X3=>X1

 

 

2)С2H6(+4NO2)->X1(H2.кат)->x2(HBr)->X3(+NaOH)->X2(+C2H5Rr)->x4 Помогите,пожайлуста!!!

Answer 1

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.
