1. 2CH4 -------> HC ≡ CH +3H2↑
CuCl HCl
2HC ≡ CH ---------------> HC ≡ C - CH = CH2
Pd
HC ≡ C - CH = CH2 + H2 ------> H2C = CH - CH = CH2
Ai(C2H5)3, TiCl4
nH2C = CH - CH = CH2 -------------------------> (- H2C - CH = CH - CH2 -)n
2.
CaC2 + H2O ---> Ca(OH)2 + HC ≡ CH
HC ≡ CH + H2 -------> H2C = CH2
H⁺
H2C = CH2 + H2O -----> H3C - CH2 - OH
Ai2O3 ZnO
2H3C - CH2 - OH ------------------> H2C = CH - CH = CH2 + H2 + 2H2O
3.
AI4C3 + 12H2O ----> 3CH4 + 4AI(OH)3
2CH4 ----> HC ≡ CH + 3H2↑
H2C = CH - CH = CH2 + Br2 -----> H2C - CH - CH = CH2
