1. Các phản ứng ứng xảy ra:

   a) \(2{C_2}{H_2}\xrightarrow{{{t^o}}}CH \equiv C – CH = C{H_2}\)

   \(CH \equiv C – CH = C{H_2} + {H_2}\xrightarrow{{Pd,{t^o}}}C{H_2} = CH – CH – C{H_2}\)

   \(nC{H_2} = CH – CH – C{H_2}\xrightarrow{{{t^o},xt}}{( – C{H_2} – CH = CH – C{H_2} – )_n}\)

   b) 

   \(2C{H_4}\xrightarrow{{{{1500}^o}C,l\ln }}CH \equiv CH + 3{H_2}\)

   \(CH \equiv CH + {H_2}\xrightarrow{{Pd,{t^o}}}C{H_2} = C{H_2}\)

   \(nC{H_2} = C{H_2}\xrightarrow{{{t^o},xt}}{( – C{H_2} – C{H_2} – )_n}\)

   c)

   \(2C{H_4}\xrightarrow{{{{1500}^o}C,l\ln }}CH \equiv CH + 3{H_2}\)

   \(CH \equiv CH + 2{H_2}\xrightarrow{{Ni,{t^o}}}C{H_3} – C{H_3}\)

   \(C{H_3} – C{H_3} + C{l_2}\xrightarrow{{as}}C{H_3} – C{H_2}Cl + HCl\)
