Write the reaction equation: C2H6-C2H4-C2H2-C2H3Cl

Ethane decomposes into ethylene and hydrogen:
C2H6 → C2H4 + H2 ↑;

Ethylene decomposes into acetylene and hydrogen:
C2H4 → C2H2 + H2 ↑;

Acetylene enters into a coupling reaction with hydrochloric acid and the result is the only reaction product – vinyl chloride:
C2H2 + HCl → C2H3Cl.
