Write the reaction equations: ethyl alcohol – ethylene – ethane – chloroethane – sodium ethylate

Let’s implement the solution:
C2H5OH = H2O + C2H4 – dehydration reaction, occurs when heated in the presence of H2SO4
H2C = CH2 + H2 = C2H6 – hydrogenation reaction;
C2H5 + Cl2 = C2H5Cl + HCl – substitution reaction;
С2Н5Cl + KOH = C2H5OH + KCl – exchange reaction;
2C2H5OH + 2Na = 2C2H5ONa + H2 – substitution reaction, sodium ethylate is formed.
The reaction equations for the synthesis of organic substances show the genetic relationship between alcohols, alkanes, alkenes. The substances are of practical importance, for example ethanol and chloroethane are solvents.
