Answer 1

Answer 2

1. \(2CH_4\underrightarrow{t^o}C_2H_2+2H_2\)

2. \(C_2H_2+H_2\rightarrow C_2H_4\)

3. \(C_2H_4+H_2O\rightarrow C_2H_5OH\)

4. \(CH_4+Cl_2\rightarrow CH_3Cl+HCl\)

5. \(Br_2+C_2H_2\rightarrow C_2H_2Br_2\)

6. \(Br_2+C_2H_4\rightarrow C_2H_4Br_2\)

7. \(3C_2H_2\rightarrow C_6H_6\)

8. \(C_2H_4+HCl\rightarrow C_2H_5Cl\)

9. \(C_6H_6+Br_2\rightarrow C_6H_5Br+HBr\)

10. \(C_2H_5Cl+NaOH\rightarrow C_2H_5OH+NaCl\)

Answer 3

2CH4\(\xrightarrow[làm.lạnh.nhanh]{1500^o}\) C₂H₂+ 2H₂\(\uparrow\)

C₂H₂+ H₂\(\xrightarrow[to]{Pd}\) C₂H₄

C₂H₄+ H₂O\(\xrightarrow[]{axit}\) C₂H₅OH

CH₄+ Cl₂\(\xrightarrow[]{as}\) CH₃Cl+ HCl

C₂H₂+ Br₂\(\rightarrow\) C₂H₂Br₂

C₂H₄+ Br₂\(\rightarrow\) C₂H₄Br₂

3C₂H₂\(\rightarrow\) C₆H₆

C₂H₄+ HCl\(\rightarrow\) C₂H₅Cl

C₆H₆+ Br₂\(\xrightarrow[to]{Fe}\) C₆H₅Br+ HBr

C₂H₅Cl+ NaOH\(\rightarrow\) C₂H₅OH+ NaCl
