Write the reaction equation: Ethane-ethylene-ethanol-acetaldehyde-acetic acid

Let’s compose the reaction equations:
Н3С – СН3 = Н2С = СН2 + Н2 – dehydrogenation reaction;
Н2С = СН2 + НОН = Н3С – СН2 – ОН – hydration reaction;
Н3С – СН2 – ОН + CuO = H3C – CH2OH + Cu + H2O – alcohol oxidation reaction, occurs when heated, acetaldehyde is formed;
Н3С – СН2О + Ag2O = H3C – COOH + 2Ag – aldehyde oxidation reaction, acetic acid is formed.
The genetic relationship between alkanes, alkenes, alcohols, aldehydes and carboxylic acids is confirmed by writing down the reaction equations.
