Write the reaction equation: C2H4- C2H6- C2H5Cl ↓ C2H2- CO2

1. Reaction of ethylene hydrogenation.
CH2 = CH2 + H2 => C2H6.
2. Ethane chlorination, UV light.
C2H6 + Cl2 = C2H5Cl + HCl.
3. Reaction of elimination.
C2H5Cl + NaOH = C2H4 + NaCl + H2O.
Dehydrogenation of ethylene.
C2H4 = C2H2 + H2.
4. Combustion of acetylene.
2C2H2 + 5O2 = 4CO2 + 2H2O.
