a) \({C_3}{H_8}\xrightarrow{{{t^o},xt}}C{H_4} + {C_2}{H_4}\)
\(2C{H_4}\xrightarrow{{{{1500}^o}C}}{C_2}{H_2} + 3{H_2}\)
\({C_2}{H_2} + {H_2}\xrightarrow{{Pd,{t^o}}}{C_2}{H_4}\)
\({C_2}{H_4} + {H_2}\xrightarrow{{Ni.{t^o}}}{C_2}{H_6}\)
\({C_2}{H_6} + B{r_2}\xrightarrow{{{t^o}}}{C_2}{H_5}Br + HBr\)
\({C_2}{H_5}Br + NaOH\xrightarrow{{}}{C_2}{H_5}OH + NaBr\)
b) \(2{C_2}{H_2}\xrightarrow{{{t^o},xt}}C{H_2} = CH – C \equiv CH\)
\(C{H_2} = CH – C \equiv CH + {H_2}\xrightarrow{{Pd,{t^o}}}C{H_2} = CH – CH = C{H_2}\)
\(nC{H_2} = CH – CH = C{H_2}\xrightarrow{{{t^o},xt}}{( – C{H_2} = CH – CH = C{H_2} – )_n}\)
