Carry out the transformation of aluminum carbide methane chloromethane ethane ethene.

Let’s show the genetic relationship of substances: AL4C3 –CH4- CH3CL – C2H4
Let’s implement the solution by applying knowledge about the methods of obtaining substances:
AL4C3 + 12 H2O = CH4 + 4 AL (OH) 3 – methane synthesis in the laboratory;
CH4 + CL2 = CH3CL + HCL – the substitution reaction occurs in the light in the presence of a catalyst;
CH3CL + 2Na + H3CCL = C2H6 + NaCL – synthesis of ethane from methane chloride, reaction of A. Würz;
C2H6 = C2H4 + H2 – ethene synthesis by dehydrogenation reaction.
Ethylene finds practical application in the production of polyethylene.
