Write the reaction equations С2H6 → C2H4 → C2H2 → acetaldehyde → CH3COOH

We write the reaction equations for the following chain:
С2H6 → C2H4 → C2H2 → acetaldehyde → CH3COOH
1. From ethanol it is necessary to obtain ethylene, from ethanol under the influence of temperature and a catalyst we obtain ethylene.
t, cat
C2H6 —> C2H4 + H2
2. Acetylene must be obtained from ethylene, under the influence of a temperature of 1200 degrees, according to the following reaction:
1200 °
C2H4 -> C2H2 + H2
3. From acetylene to obtain acetaldehyde by the action of mercury sulfate
НgSO4
C2H2 + H2O -> CH3 – COH
4. Next, we obtain acetic acid from acetaldehyde by adding copper hydroxide
CH3OH + 2 Cu (OH) 2 -> CH3COOH + Cu2O + 2H2O
