Carry out the transformations: 1) methane – methanal – methanol – chloromethane – ethane – ethanol

Carry out the transformations: 1) methane – methanal – methanol – chloromethane – ethane – ethanol – ethanic acid – methane 2) acetylene – ethanol – ethylene – acetic acid – acetic acid anhydride – acetic acid

A) 1) C2H4 + H2O → C2H5OH;

2) C2H5OH → C2H4 + H2O;

3) We obtain acetic acid from ethylene in two stages:

C2H4 + H2O → C2H5OH;

C2H5OH + O2 → CH3COOH + H2O;

4) 2CH3COOH → C4H6O3 + H2O.

B) 1) CH4 + O2 → HCHO;

2) HCHO + H2 → CH3OH;

3) CH3OH + HCl → CH3Cl + H2O;

4) 2CH3Cl + 2Na → C2H6 + 2NaCl;

5) We get ethanol from ethane in two stages:

C2H6 + Cl2 → C2H5Cl + HCl;

C2H5Cl + NaOH → C2H5OH + NaCl;

6) CH3COOH → CH4 + CO2.
