Make the equation: Ethane-ethanal-ethanol

Let’s write down the chain of transformations:
C2H2 – CH3 – CHO – C2H5 – OH;
Let’s compose the equations:
С2Н2 + Н2О = Н2С = СН – ОН = Н3С – СНО – hydration reaction, occurs in water vapor, with the participation of a catalyst, vinyl alcohol is released, which is unstable and undergoes isomerization, the final product of the reaction is acetaldehyde;
Н3С – СНО + Н2 = С2Н5 – ОН – reduction of acetaldehyde with hydrogen to ethanol;
The reactions show the bond of alkynes with aldehydes and alcohols. Ethanol is used as a solvent.
