Write the reaction equation: CH4-CH3CL-C2H6-C2H5CL-C3H8

Let us write down the reaction equations for the transformation chain:
CH4 + Cl2 = CH3Cl + HCL – substitution reaction, occurs in the light, methane chloride is obtained;
2CH3Cl = 2Na = C2H6 + 2NaCl – Wurtz reaction, ethane was formed;
C2H6 + Cl2 = C2H5Cl + HCl – substitutions, chloroethane was released;
С2Н5Cl + 2Na + CH3Cl = C3H8 + 2NaCl – Wurtz reaction, propane was obtained;
The reaction products are of practical importance. Ethane and propane in natural gas are used as fuel. Halogenated derivatives – chloromethane, chloroethane – are used as solvents. The reactions show the bond between alkanes, alkenes.
