Câu 1.
\(2CH_4\rightarrow\left(t^o,làm.lạnh.nhanh\right)C_2H_2+2H_2\)
\(C_2H_2+H_2\rightarrow\left(t^o,Pb\right)C_2H_4\)
\(C_2H_4+H_2O\rightarrow\left(t^o,H_2SO_4\right)C_2H_5OH\)
\(C_2H_5OH+O_2\rightarrow\left(men.giấm\right)CH_3COOH+H_2O\)
\(C_2H_5OH+CH_3COOH\rightarrow\left(t^o,H_2SO_4\right)CH_3COOC_2H_5+H_2O\)
Câu 2.
\(CaC_2+2H_2O\rightarrow C_2H_2+Ca\left(OH\right)_2\)
\(C_2H_2+H_2\rightarrow\left(t^o,Pb\right)C_2H_4\)
\(C_2H_4+H_2O\rightarrow\left(t^o,H_2SO_4\right)C_2H_5OH\)
\(C_2H_5OH+O_2\rightarrow\left(men.giấm\right)CH_3COOH+H_2O\)
Đúng 2
