Question

Viết PTHH thực hiện dãy chuyển hoá sau.Ghi rõ điều kiện nếu có?

C₂H₄–>C₂H₅OH—>CH₃COOH—>CH₃COOC₂H₅—>CH₃COONa

 

Answer 1

\(C_2H_4+H_2O\underrightarrow{t^o,H^+}C_2H_5OH\)

\(C_2H_5OH+O_2\underrightarrow{men.giấm}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH\underrightarrow{t^o,H^+}CH_3COOC_2H_5+H_2O\)

\(CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\)

Answer 2

C₂H₄+H₂O-to, xt->C₂H₅OH

C₂H₅OH + O₂ to→ CH₃COOH + H₂O

CH₃COOH+C₂H₅OH-to, H₂SO₄>CH₃COOC₂H₅+H₂O

CH₃COOC₂H₅ +NaOH->CH₃COONa+ C₂H₅OH

 

Answer 3

\(C_2H_4+H_2O\rightarrow C_2H_5OH\)

\(C_2H_5OH+O_2\rightarrow CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH\leftrightarrow CH_3COOC_2H_5+H_2O\)

\(CH_3COOC_2H_5+H_2O\rightarrow C_2H_5OH\)
