Theo chiều từ trái sang, từ trên xuống nhé

\(C_2H_2+H_2\underrightarrow{t^o,Pd,PbCO_3}C_2H_4\)
\(C_2H_4+H_2O\underrightarrow{H^+,t^o}C_2H_5OH\)

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

\(CH_3COOH+C_2H_5OH\underrightarrow{H_2SO_{4\left(đ\right)},t^o}CH_3COOC_2H_5+H_2O\)

\(CH_3COOC_2H_5+NaOH\underrightarrow{t^o}CH_3COONa+C_2H_5OH\)

\(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)

\(2C_2H_5OH+2Na\rightarrow2C_2H_5ONa+H_2\)

\(2CH_3COOH+CuO\rightarrow\left(CH_3COO\right)_2Cu+H_2O\)

\(CH_3COOC_2H_5+NaOH\underrightarrow{t^o}CH_3COONa+C_2H_5OH\)

\(C_2H_5OH+3O_2\underrightarrow{t^o}2CO_2+3H_2O\)

Answer 2

[Kudo Shinichi]

\(C_2H_2+C_2H_4\xrightarrow[t^o]{Pd\text{/}PdCO_3}C_2H_4\\ C_2H_4+H_2O\xrightarrow[H^+]{t^o}C_2H_5OH\\ C_2H_5OH+O_2\underrightarrow{\text{men giấm}}CH_3COOH+H_2O\\ CH_3COOH+C_2H_5OH\xrightarrow[t^o]{H_2SO_{4\left(đặc\right)}}CH_3COOC_2H_5+H_2O\\ CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\)

\(C_2H_4+Br_2\rightarrow C_2H_4Br_2\\ C_2H_5OH+Na\rightarrow C_2H_5ONa+\dfrac{1}{2}H_2\\ 2CH_3COOH+CuO\rightarrow\left(CH_3COO\right)_2Cu+H_2O\\ CH_3COOC_2H_5+KOH\rightarrow CH_3COOK+C_2H_5OH\\ C_2H_5OH+3O_2\underrightarrow{t^o}2CO_2+3H_2O\)
