Make the equation: Ethylene-ethanol-acetaldehyde-acetic acid-water

1) When ethylene interacts with water in the presence of H2SO4 and when exposed to high temperatures, ethanol is formed:

C2H4 + H2O → C2H5OH;

2) Ethanol reacts with copper (II) oxide during heating and it turns out – acetaldehyde, pure copper and water:

C2H5OH + CuO → CH3COH + Cu + H2O;

3) In the process of interaction of acetaldehyde with silver (I) oxide in the presence of ammonia and water, acetic acid and silver are formed:

CH3COH + Ag2O → CH3COOH + Ag;

4) Acetic acid is oxidized to carbon dioxide and water:

CH3COOH + 2O2 → 2CO2 + 2H2O.
