Write the reaction equation: CH3Cl → C2H6 → C2H5Cl → C4H10 → C4H8 ↓ CO2

Let’s execute the solution, write down the equations of processes for organic substances:

Methane chloride – ethane – chloroethane – butane – butene – carbon monoxide (2)

2СН3Cl + 2Na = CH3 – CH3 + 2NaCl – ethane was obtained by the Wurtz reaction;
CH3 – CH3 + Cl2 = CH3 – CH2Cl + HCl – substitution, chloroethane was formed;
2CH3CH2Cl + 2Na = 2NaCl + CH3 – CH2 – CH2 – CH3 (C4H10) – butane is released;
CH3 – CH2 – CH2 – CH3 = H2 + CH3 – CH2 – CH = CH2 – dehydrogenation, butene formed;
СН3 – СН2 – СН = СН2 + 6О2 = 4СО2 + 4Н2О + Q – combustion, heat, carbon dioxide, water are released.
The solution shows the relationship between organic and inorganic substances by the example of methane chloride, carbon monoxide (2).
