g, CH₃ - COOH + CH₃ - CH₂ - OH \(\xrightarrow[\leftarrow]{H_2SO_4d,t^O}\) 

 

Answer 1

\(a) 2C_2H_5OH + 2K \to 2C_2H_5OK + H_2\\ b) 2CH_3COOH + CaCO_3 \to (CH_3COO)_2Ca + CO_2 + H_2O\\ c) 2CH_3COOH + ZnO \to (CH_3COO)_2Zn + H_2O\\ d) CH_3COOH + KOH \to CH_3COOK + H_2O\\ e) CH_4 + Cl_2 \xrightarrow{ánh\ sáng} CH_3Cl + HCl\\ f) CH≡CH + 2Br_2 \to CHBr_2-CHBr_2\\ g) CH_3-COOH + CH_3-CH_2-OH \buildrel{{H_2SO_4}}\over\rightleftharpoons CH_3-COO-CH_2-CH_3 + H_2O\)

Answer 2

2C2H5OH + 2K --> 2C2H5OK + H2

CH3COOH + CaCO3 --> (CH3COO)2Ca + CO2 + H2O

2CH3COOH + ZnO --> (CH3COO)2Zn + H2O

CH3COOH + KOH --> CH3COOK + H2O

CH4+ Cl2 -as-> CH3Cl + HCl 

CH3\(\equiv\)CH3 + Br2 --> C2H5Br + HBr
