Write the reaction equation: C2H2 → CH3COH → X → CH3COONa → CH3COOC2H5 → X

1) C2H2 + H2O = CH3CHO (acetaldehyde is formed);
2) CH3CHO + Ag2O = CH3COOH + 2Ag (acetic acid is formed);
3) CH3COOH + NaOH = CH3COONa + H2O (sodium acetate is formed);
4) CH3COONa + C2H5OH = CH3COOC2H5 + NaOH (ethyl ester of acetic acid is formed);
5) CH3COOC2H5 + H2O = CH3COOH + C2H5OH (acetic acid is formed).
