1. $CH_3COONa+NaOH\buildrel{{CaO, t^o}}\over\to CH_4+Na_2CO_3$

   $2CH_4\buildrel{{1500^oC}}\over\to C_2H_2+3H_2$

   $2C_2H_2\buildrel{{CuCl_2, t^o}}\over\to CH\equiv C-CH=CH_2$

   $CH\equiv C-CH=CH_2+H_2\buildrel{{Pd/PbCO_3, t^o}}\over\to CH_2=CH-CH=CH_2$

   $nCH_2=CH-CH=CH_2\buildrel{{t^o, p, xt}}\over\to (-CH_2-CH=CH-CH_2-)_n$

2. \(\begin{array}{l}
   C{H_3}COONa + NaOH \to N{a_2}C{O_3} + C{H_4}\\
   2C{H_4} \to {C_2}{H_2} + 3{H_2}\\
   2CH \equiv CH \to C{H_2} = CH – C \equiv CH\\
   C{H_2} = CH – C \equiv CH + {H_2} \to C{H_2} = CH – CH = C{H_2}\\
   nC{H_2} = CH – CH = C{H_2} \to {( – C{H_2} – CH = CH – C{H_2})_n}
   \end{array}\)
