Write the reaction equation: С2Н2 → СН3СОН → СН3СООН → СН3СООNa.

1) To obtain acetaldehyde from acetylene, you must use a nominal reaction – Kucherov’s reaction:

C2H2 + H2O → CH3COH;

2) Acetic aldehyde is one of the few substances that enters into a silver mirror reaction, during which acetic acid is formed:

CH3COOH + Ag2O → CH3COOH;

3) Acetic acid reacts with metallic sodium and it turns out – sodium acetate and hydrogen is released:

2СН3СООН + 2Na → 2СН3СООNа + H2 ↑.
