Write the reaction equation in accordance with the transformation scheme: CaC2- C2H2 – C2H4 – C2H5Br – C2H5NH2- + H2SO4 – X (+ H2SO4 is above the arrow)

Let us write down the reaction equations for the transformation chain:
CaC2 + 2H2O = Ca (OH) 2 + C2H2 – hydrolysis of calcium carbide occurs at normal conditions, gaseous acetylene is released;
C2H2 + H2 = C2H4 – addition, ethylene was obtained;
Н2С = СН2 + HBr = H3C – CH2Br – additions, hydrogen bromide is released;
Н3С – СН2Br + NH3 = C2H5NH2 + HCl – exchange occurs upon heating, ethylamine is formed;
2С2Н5NH2 + H2SO4 = (H3C – CH2 – NH3) 2SO4 – the ethylammonium sulfate salt is obtained, in the course of the reaction ethylamine exhibits the properties of a base.
The reactions show the connection of inorganic and organic substances, as well as unsaturated hydrocarbons with amines. The reaction of interaction of amines with sulfuric acid is used to purify aniline from impurities during its synthesis.
