Make the equation: Methane-chloromethane-ethane-ethene – bromoethane-butane 

Let’s carry out the solution of the chain of transformations for organic substances:

CH4 – CH3Cl – C2H6 – C2H4 – CH4Br – C4H10

CH4 + Cl2 = CH3Cl + HCl – substitutions, chloromethane obtained;
2СН3Cl + 2Na = 2NaCl + C2H6 – ethane is released during the Wurtz reaction;
C2H6 = H2 + C2H4 – dehydrogenation, ethene was formed;
C2H4 + HCl = C2H5Cl – addition, chloroethane was obtained;
2С2Н5Cl + 2Na = C4H10 + 2NaCl – butane evolved;
С4Н10 = С3Н6 + СН4 – thermal cracking, methane was formed;
CH4 + Br2 = CH3Br + HBr – bromomethane obtained;
CH3Br + 2Na + C3H7Br = C4H10 + NaBr – butane formed.
The solution shows the connection of hydrocarbons, homologues of the alkane class. The reaction products are of practical importance, for example, chloroethane, bromomethane are used as solvents.
