Cho chuỗi phản ứng sau: $A → C_2H_5OH → B → CH_3COONa → C → C_2H_2$ Ch

Cho chuỗi phản ứng sau:

$A → C_2H_5OH → B → CH_3COONa → C → C_2H_2$

Chất A, B, C lần lượt là

• A. $C_6H_{12}O_6, CH_3COOH, CH_4.$
• B. $C_6H_6, CH_3COOH, C_2H_4.$
• C. $C_6H_{12}O_6, C_2H_5ONa, CH_4$.
• D. $ C_2H_4, CH_3COOH, C_2H_5ONa.$

$C_6H_{12}O_6 \xrightarrow{lên \ men}  2C_2H_5OH + 2CO_2$

$C_2H_5OH  +   O_2 \xrightarrow{ Men \ giấm} CH_3COOH$

$CH_3COOH+ Na \rightarrow CH_3COONa + 1/2H_2$

$CH_3COONa + NaOH \xrightarrow{CaO, t^o} Na_2CO_3 + CH_4$

$2CH_4  \xrightarrow{làm \ lạnh \ nhanh , 1500^oC} C_2H_2 + 3H_2$
