CH3COONa + NaOH---CaO,\(t^o\)---> CH4 + Na2CO3
2CH4 --t\(^o=1500^oC,\)làm lạnh nhanh--> C2H2 + 3H2
C2H2 + H2 --\(t^o,xt,Pd\)--> C2H4
C2H4 + H2O --\(t^o,H2SO4\)--> C2H5OH
3C2H5OH + 3C6H6O -> 4C6H6 + 6H2O
C6H6 + HNO3 --\(t^o,H2SO4\)--> C6H5NO2 + H2O

\(CH_2=CH_2+H_2O\rightarrow\left(H_2SO_4,t^o\right)CH_3CH_2OH\\ CH_3CH_2OH+CH_3COOH⇌\left(H^+,t^o\right)CH_3COOC_2H_5+H_2O\)

Câu 1:
\(2CH_4\underrightarrow{^{1500^oC,lln}}C_2H_2+3H_2\)
\(2CH\equiv CH\underrightarrow{t^o,xt}CH_2=CH-C\equiv CH\)
\(CH_2=CH-C\equiv CH+H_2\underrightarrow{t^o,Ni}CH_2=CH-CH=CH_2\)
\(nCH_2=CH-CH=CH_2\underrightarrow{^{t^o,p,xt}}\left(-CH_2-CH_2-CH_2-CH_2-\right)_n\)
Câu 2:
\(CH_3COONa+NaOH\underrightarrow{^{t^o,CaO}}CH_4+Na_2CO_3\)
\(2CH_4\underrightarrow{^{1500^oC,lln}}C_2H_2+3H_2\)
\(C_2H_2+H_2\underrightarrow{t^o,Pd}C_2H_4\)
\(C_2H_4+H_2O\underrightarrow{t^o,xt}C_2H_5OH\)

Chọn đáp án C
(2) C2H5OH + CuO → CH3CHO + Cu + H2O
(3) C2H2 + H2O → CH3CHO (Xúc tác HgSO4, H2SO4 80oC)
(5) HCOOCH=CH2 + NaOH → HCOONa + CH3CHO
(7) C2H4 + ½O2 → CH3CHO (Xúc tác PdCl2)
⇒ Chọn C
\(C_2H_2 + H_2 \xrightarrow{t^o,xt} C_2H_4\\ C_2H_4 + H_2O \xrightarrow{t^o,xt} C_2H_5OH\\ C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ CH_3COOH + NaOH \to CH_3COONa + H_2O\)
\(C_2H_2+H_2\underrightarrow{^{Pd,t^0}}C_2H_4\)
\(C_2H_4+H_2O\underrightarrow{^{H_2SO_4,170^0C}}C_2H_5OH\)
\(C_2H_5OH+O_2\underrightarrow{^{\text{men giấm}}}CH_3COOH+H_2O\)
\(CH_3COOH+Na\rightarrow CH_3COONa+\dfrac{1}{2}H_2\)
