Hoàn thành chuỗi phản ứng sau: a/ CaC2-> C2H2-> C2H4->C2H4Br2. CaC2-> C2H2Br4 b/ Al4C3-> CH4-> C2H2-> C2H6-> C2H5Cl

Đáp án:

a, 

$CaC_2+2H_2O\to Ca(OH)_2+C_2H_2$
$C_2H_2+H_2\xrightarrow{{Pd/PbCO_3, t^o}} C_2H_4$

$C_2H_4+Br_2\to C_2H_4Br_2$

$C_2H_2+2Br_2\to C_2H_2Br_4$

b, 

$Al_4C_3+12H_2O\to 3CH_4+4Al(OH)_3$

$2CH_4\xrightarrow{{1500^oC, lln}} C_2H_2+3H_2$
$C_2H_2+2H_2\xrightarrow{{Ni, t^o}} C_2H_6$

$C_2H_6+Cl_2\xrightarrow{{as}} C_2H_5Cl+HCl$
