Question

B1:

Thực hiện dãy chuyển hóa sau. (ghi rõ đk nếu có)

a. C₂H₄ ➝ C₂H₅OH➞ CH₃CHO➜ CH₃COOH➜CH₃COOK

b. CH₃COOH ➞ CH₃COONa ➜ CH₄ ➜ C₂H₂➜C₂H₄

Answer 1

\(a.\left(1\right)C_2H_4+H_2O\underrightarrow{axit}C_2H_5OH\left(2\right)C_2H_5OH+CuO\rightarrow CH_3CHO+Cu+H_2O\\ \left(3\right)2CH_3CHO+O_2\underrightarrow{t^o,xt}2CH_3COOH\\ \left(4\right)CH_3COOH+K\rightarrow CH_3COOK+\frac{1}{2}H_2\\ b.\left(1\right)CH_3COOH+Na\rightarrow CH_3COONa+\frac{1}{2}H_2\\ \left(2\right)CH_3COONa+NaOH\rightarrow CH_4+Na_2CO_3\\ \left(3\right)2CH_4\underrightarrow{lln}C_2H_2+3H_2\\ \left(4\right)C_2H_2+H_2\underrightarrow{t^o,xt}C_2H_4\)
