Let us write down the reaction equations for a given chain of compounds.
CaC2 + H2O = C2H2 + Ca (OH) 2.
In this reaction, calcium carbide and water interact, resulting in the formation of acetylene and calcium hydroxide. Hydrolysis reaction.
C2H2 + H2 = C2H4.
Hydrogenation reaction. When acetylene interacts with hydrogen, ethene is formed.
C2H4 + HBr = C2H5Br.
Hydrohalogenation reaction. The interaction of ethene and hydrogen bromide forms bromoethane.
C2H5Br + NH3 = C2H5NH2 + HBr.
When bromoethane reacts with ammonia, ethylamine and hydrogen bromide are formed.
C2H5NH2 + N2O3 = C2H5NO2 + H2O + N2.
