Make the reaction equations: calcium carbide → ethin → benzene → nitrobenzene → aniline → phenylammonium chloride

1) CaC2 + H2O -> Ca (OH) 2 + C2H2

2) C2H2 -> (trimerization, C act., T °) C6H6

3) C6H6 + HNO3 (c.) -> (H2SO4 (c.)) C6H5NO2 + H2O

4) C6H5NO2 + 3H2 -> (Ni) C6H5NH2 + H2O

5) C6H5NH2 + HCl = C6H5NH3 (+) Cl (-)
