Write the reaction equation: CO (2 valence) -CH4-CH3Cl-C2H6-CO (4 valence)

CO → CH4 → СН3Сl → С2Н6 → CO2

1) CO + 3H2 ↑ → CH4 + H2O (carbon monoxide, hydrogen, methane, water);

2) CH4 + Cl2 → CH3Cl + HCl (methane, chlorine, chloromethane, hydrochloric acid);
3) 2СН3Сl + 2Nа → С2Н6 + 2NаСl (chloromethane, sodium, ethane, sodium chloride);

4) C2H6 + O2 → CO2 ↑ + H2O (ethane, oxygen, carbon dioxide, water).
