Make up the reaction equations in accordance with the scheme: CH4 – C2H2 – C6H6 – C6H5Br.

Make up the reaction equations in accordance with the scheme: CH4 – C2H2 – C6H6 – C6H5Br. indicate the condition of the reactions and name the substances

Let’s compose equations for organic compounds:
1. Methane – acetylene – benzene – bromobenzene.
2CH4 = C2H2 + 3H2 – decomposition occurs when heated to 1500 degrees, acetylene is obtained;
3C2H2 = C6H6 – trimerization is carried out on hot coal, benzene is formed;
C6H6 + Br2 = C6H5Br + HBr – substitutions, bromobenzene is released.
2. The decision confirms the relationship between the classes of hydrocarbons: alkanes, alkynes, arenes. The reaction products find practical application, for example, bromobenzene is used as a solvent.
