Question

CH4-->X1--->X2--->X3---->X4----->X5----->X6-----> X7----->X8----->C2Cl6

Answer 1

2CH4(t) -> C2H2+3H2
C2H2+H2(t)-> C2H4
C2H4+HCl->C2H5Cl
C2H5Cl+KOH->C2H5OH+KCl
C2H5OH+CuO(t)->CH3-COH+Cu+H2O
CH3-COH+Ag2O(t) ->CH3-COOH+2Ag
CH3-COOH+NaOH->CH3-COONa+H2O
2CH3-COONa+2H2O(электролиз)  ->C2H6+2CO2+2NaOH+H2
C2H6+3Cl2(t) ->C2Cl6+6HCl
