Giải thích các bước giải:

Các chất phản ứng với rượu etylic (C2H5OH): Na, CuO

(1) C2H5OH + Na → C2H5ONa + $\frac{1}{2}$H2

(2) C2H5OH + CuO → CH3CHO + Cu + H2O (phản ứng oxi hóa không hoàn toàn)

Các chất phản ứng với axit axetic (Ch3COOH): Na, Fe, NaOH, KHCO3, Na2CO3, CuO

(1) CH3COOH + Na → CH3COONa + $\frac{1}{2}$H2

(2) CH3COOH + Fe → (CH3COO)2Fe + $\frac{1}{2}$H2

(3) CH3COOH + NaOH → CH3COONa + H2O

(4) CH3COOH + KHCO3 → CH3COOK + CO2 + H2O

(5) 2CH3COOH + Na2CO3 → 2CH3COONa + CO2 + H2O

(6) 2CH3COOH + CuO → (CH3COO)2Cu + H2O

Các chất phản ứng với este etyl axetat (CH3COOC2H5): NaOH

(1) CH3COOC2H5 + NaOH → C2H5OH + CH3COONa
