Write the reaction equation: C₂H₂ – CH₃CHO – CH₃COOH – CH₃COONa – CH₃COOH – H₂

Let’s implement the solution for the transformation chain:
Acetylene – ethanal – acetic acid – sodium acetate – acetic acid – hydrogen
С2Н2 + Н2О = Н2С = СНОН (vinyl alcohol) = СН3СОН – hydration, ethanal is formed;
СН3 – СОН + Ag2O = CH3COOH + 2Ag – qualitative reaction to aldehyde, acetic acid and silver are released;
CH3COOH + NaOH = CH3COONa + H2O – exchange, sodium acetate was obtained;
CH3COONa + H2O = CH3COOH + NaOH – acetic acid formed during hydrolysis;
2СН3СООН + 2Na = 2CH3COONa + H2 – substitutions, hydrogen is evolved.
The solution shows the relationship between organic and inorganic substances using the example of acetylene and hydrogen, as well as between hydrocarbons and oxygen-containing compounds.
