Question

Viết PTHH của phản ứng cho chuỗi chuyển hóa sau:

CaC₂  → C₂H₂  →   C₂H₄  → C₂H₄Br₂

                               ↓

                C₂H₂Br₄

Answer 1

\(CaC_2+2H_2O\rightarrow Ca\left(OH\right)_2+C_2H_2\)

\(C_2H_2+H_2\underrightarrow{^{t^o,Pd/PbCO_3}}C_2H_4\)

\(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)

\(C_2H_2+2Br_2\rightarrow C_2H_2Br_4\)

Answer 2

\(\left(1\right)CaC_2+2H_2O\rightarrow Ca\left(OH\right)_2+C_2H_2\\ \left(2\right)C_2H_2+H_2\xrightarrow[t^0]{xt}C_2H_4\\ \left(3\right)C_2H_4+Br_2\rightarrow C_2H_4Br_2\\ \left(4\right)C_2H_2+2Br_2\rightarrow C_2H_2Br_4\)
