Make up the reaction equation: С – СН4 – С2Н6 – С2Н4 – С2Н5ОН – С2Н4О – СН3СООН.

C + 2H2 = CH4 – reaction of the compound, methane was obtained;
CH4 + Cl2 = CH3Cl + HCl – substitutions, methane chloride was released;
2CH3Cl + 2Na = C2H6 + 2NaCl – Wurtz reaction, ethane was formed;
C2H6 = C2H4 + H2 – dehydrogenation, ethylene was obtained;
Н2С = СН2 + Н2О = С2Н5ОН – hydration, ethanol was formed;
С2Н5ОН + CuO = CH3 – CHO + Cu + H2O – oxidation, acetaldehyde is released;
CH3 – CHO + Ag2O = CH3COOH + 2Ag – oxidation of aldehyde, acetic acid obtained.
These reactions show the connection of an inorganic substance – carbon and an organic substance – acetic acid.
