a,

$C_2H_5COONa+NaOH\buildrel{{CaO, t^o}}\over\longrightarrow C_2H_6+Na_2CO_3$

$C_2H_6+Cl_2\buildrel{{\text{askt}}}\over\longrightarrow C_2H_5Cl+ HCl$ 

$C_2H_5Cl+NaOH\buildrel{{C_2H_5OH, t^o}}\over\longrightarrow C_2H_4+NaCl+H_2O$

$nC_2H_4\buildrel{{t^o, p, xt}}\over\longrightarrow (CH_2-CH_2)_n$

b,

$C_3H_8\buildrel{{xt, t^o}}\over\longrightarrow CH_4+C_2H_4$

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

$C_2H_2+H_2\buildrel{{Pd/PbCO_3, t^o}}\over\longrightarrow C_2H_4$
