Question

Viết ptpu theo chuỗi sau và ghi các điều kiện phản ứng

a/ butan--> etan--> etyl clorua --> butan --> metan --> cacbon

b/ nhôm cacbua --> metan --> metyl clorua --> etan --> etyl clorua

Answer 1

a,

\(C_4H_{10}\underrightarrow{^{to}}C_2H_4+C_2H_6\)

\(C_2H_6+Cl_2\underrightarrow{^{als}}C_2H_5Cl+HCl\)

\(2C_2H_5Cl+Na\underrightarrow{^{to}}C_4H_{10}+2NaCl\)

\(C_4H_{10}\underrightarrow{^{to}}CH_4+C_3H_6\)

\(CH_4+2Cl_2\rightarrow C+4HCl\)

b,

\(Al_4C_3+12HCl\rightarrow3CH_4+4AlCl_3\)

\(CH_4+Cl_2\underrightarrow{^{as}}CH_3Cl+HCl\)

\(2CH_3Cl+Na\underrightarrow{^{to}}C_2H_6+2NaCl\)

\(C_2H_6+Cl_2\underrightarrow{^{as}}C_2H_5Cl+HCl\)

Answer 2

a) - C4H10 -to-> C2H6 + C2H4

- C2H6 + Cl2 --> C2H5Cl + HCl

- 2C2H5Cl + Na --> C4H10 + 2NaCl

- C4H10 -to-> CH4 + C3H6

- CH4 --to--> C + 2H2

b) - Al4C3 + 12H2O --> 4Al(OH)3 + 3CH4

- CH4 + Cl2 --> CH3Cl + HCl

- 2CH3Cl + Na -to-> C2H6 + 2NaCl

- C2H6 + Cl2 --> C2H5Cl + HCl
