Question

Answer 1

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

\(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)

\(C_2H_4+H_2\underrightarrow{^{t^{o,}Ni}}C_2H_6\)

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

Answer 2

\(C_2H_2+H_2\xrightarrow[xt]{t^0}C_2H_4\\ C_2H_4+H_2\xrightarrow[xt]{t^0}C_2H_6\\ C_2H_6+Cl_2\xrightarrow[sáng]{ánh}C_2H_5Cl+HCl\\ C_2H_4+Br_2\xrightarrow[]{}C_2H_4Br_2\)
