Write down the reaction equations that can be used to carry out the following transformations: calcium carbide-acetylene-acetaldehyde-acetic acid-acetic-ethyl ether-ethyl alcohol. Which of the transformations are hydrolysis reactions?

Let us write the given reaction equations:

CaC2 + 2H20 = Ca (OH) 2+ H2C2 (hydrolysis of calcium carbide is a laboratory method for producing ethyne, methane pyrolysis is used in industry).
H2C2 + H2O = CH3COH (the addition of a water molecule to ethine leads to the formation of acetaldehyde – Kucherov’s reaction, the intermediate product of the reaction is vinyl alcohol).
CH3COH + 2Cu (OH) 2 = CH3COOH + Cu2O + 2H20 (ethanic acid is obtained by oxidation of ethanal).
CH3COOH + CH3CH2OH = CH3COOCH2CH3 + H2O (reversible reaction of esterification – obtaining an ester, the equilibrium of the system obeys the La Chatelier principle).
CH3COOCH2CH3 + H2O = CH3COOH + CH3CH2OH (in an acidic medium, the ester is hydrolyzed to the starting carboxylic acid and alcohol).
Hydrolysis reactions (exchange decomposition of a substance with water) are 1 and 5.
