Write the reaction equations: ethane-ethene-ethyne-benzene.

Let’s compose the reaction equations for the transformation chain. The substances indicated in the chain refer to hydrocarbons: C2H6 – ethane; C2H4 – ethene or ethylene; ethylbenzene – C6H5 – C2H5.
1.C2H6 = C2H4 + H2 – dehydrogenation reaction.
2. H2C = CH2 + HCL = H3C – CH2CL (C2H5CL – chloroethane) – addition reaction.
3.C6H6 + C2H5CL = C6H5 – C2H5 + HCL – alkylation reaction
Ethylbenzene is the basis for the production of styrene, which is used in industry for the production of plastics and rubber.
