\(CaC_2\underrightarrow{\left(1\right)}CH=CH\)\(\underrightarrow{\left(2\right)}C_2H_4\underrightarrow{\left(3\right)}C_2H_5OH\)\(\underrightarrow{\left(4\right)}CH_3COOH\underrightarrow{\left(5\right)}CH_3COOC_2H_5\)

Answer 1

\((1) CaC_2 + 2H_2O \to Ca(OH)_2 + C_2H_2\\ (2) C_2H_2 + H_2 \xrightarrow{t^o,PbCO_3} C_2H_4\\ (3) C_2H_4 + H_2O \xrightarrow{t^o,H^+} C_2H_5OH\\ (4) C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ (5) CH_3COOH + C_2H_5OH \buildrel{{H_2SO_4}}\over\rightleftharpoons CH_3COOC_2H_5 + H_2O\)
