C2H4 -> C2H5OH -> CH3COOH -> CH3COOC2H5 -> CH3COONa

a) C2H4 + H2O -> C2H5OH

C2H5OH + O2 → CH3COOH + H2O

CH3COOH + C2H5OH → CH3COOC2H5 + H2O

CH3COOC2H5 + NaOH → C2H5OH + CH3COONa

b)

6) C2H5OH + O2 → CH3COOH + H2O

7) CH3COOH + NaOH -> CH3COONa + H2O

8) CH3COOH + C2H5OH → CH3COOC2H5 + H2O

c)

12) C2H4 + H2O -> C2H5OH

13) C2H5OH + O2 → CH3COOH + H2O

14) Zn + 2CH3COOH → (CH3COO)2Zn + H2

15) CH3COOH + C2H5OH → CH3COOC2H5 + H2O
