Write the reaction equations: CaC2-C2H2-CH3CHO-CH3CH2OH

Let’s execute the solution:
CaC2 + 2H2O = C2H2 + Ca (OH) 2 – hydration reaction of calcium carbide, ethin is obtained;
С2Н2 + Н2О = Н2С = СНОН (vinyl alcohol) = Н3С – СОН – hydration of ethine, Kucherov’s reaction, an intermediate product of vinyl alcohol is released, which is isomerized, then ethanal is formed;
Н3С – СОН + Н2 = Н3С – СН2 – ОН – reduction of ethanal to ethyl alcohol.
These reactions show the relationship between inorganic and organic compounds. The reaction products find practical applications, for example, acetylene is used for cutting and welding metals, and ethanol is used as fuel.
