Write the reaction equation: CH4- C2H6- C2H5CL- CH3CH2OH- ethyl butyric acid

1) To obtain ethane from methane, it is necessary to carry out two reactions. First, methane reacts with chlorine, it turns out – chloromethane and hydrochloric acid:

CH4 + Cl2 → CH3Cl + HCl;

Next, sodium metal is added to chloromethane, and ethane and sodium chloride are obtained:

CH3Cl + Na → C2H6 + NaCl (the presented reaction is called the Wurtz reaction)

2) Ethane reacts with chlorine, it turns out – chloroethane and hydrochloric acid:

C2H6 + Cl2 → C2H5Cl + HCl;

3) When chloroethane interacts with sodium hydroxide, ethanol and sodium chloride are formed:

C2H5Cl + NaOH → C2H5OH + NaCl;

4) To obtain ethyl ester of butyric acid from ethanol, it is necessary to add butyric acid to ethanol, as a result we get:

С3H7COOH + C2H5OH → C3H7COOC2H5 + H2O.
