Glucozơ--->C₂H₅OH--->CH₃COOC₂H₅---->CH₃COONa---->CH₄

Answer 1

C6H12O6 => (men rượu,t^o) 2CO2 + 2C2H5OH

C2H5OH + CH3COOH => (pứ hai chiều, t^o,H2SO4đ) CH3COOC2H5 + H2O

CH3COOC2H5 + NaOH => CH3COONa + C2H5OH

CH3COONa + NaOH => (t^o,CaO) Na2CO3 + CH4

Answer 2

1) \(C_6H_{12}O_6+H_2O\rightarrow2C_2H_5OH+2CO_2\)

2)\(C_2H_5OH+CH_3COOH\rightarrow CH_3COOC_2H_5+H_2O\)

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

4)\(CH_3COONa+NaOH\rightarrow CH_4+Na_2CO_3\)

Answer 3

C6H12O6 => (men rượu,to) 2CO2 + 2C2H5OH

C2H5OH + CH3COOH <=> to,H2SO4đ) CH3COOC2H5 + H2O

CH3COOC2H5 + NaOH => CH3COONa + C2H5OH

CH3COONa + NaOH => (to,CaO) Na2CO3 + CH4
