a)
$4Al+3C\xrightarrow{t^o} Al_4C_3$
$Al_4C_3+12H_2O\xrightarrow{} 4Al(OH)_3 + 3CH_4$
$CH_4 + Cl_2\xrightarrow{á/s} CH_3Cl+HCl$
$CH_3Cl + Cl_2\xrightarrow{á/s} CH_2Cl_2+HCl$
$CH_2Cl_2 + Cl_2\xrightarrow{á/s} CHCl_3+HCl$
$CHCl_3 + Cl_2\xrightarrow{á/s} CCl_4+HCl$
b)
$CH_3COOH+NaOH\xrightarrow{} CH_3COONa + H_2O$
$CH_3COONa+H_2O\xrightarrow{t^o,CaO} CH_4 + Na_2CO_3$
$CH_4 + Cl_2\xrightarrow{á/s} CH_3Cl+HCl$
$2CH_3Cl +2Na\xrightarrow{t^o} C_2H_6+2NaCl$
$C_2H_6\xrightarrow{t^o,xt}C_2H_4+H_2$
c)
$C_4H_{10}\xrightarrow{t^o,xt}C_2H_6+C_2H_4$
$C_2H_6+Cl_2\xrightarrow{á/s}C_2H_5Cl+HCl$
$2C_2H_5Cl+2Na\xrightarrow{t^o}C_4H_{10}+2NaCl$
$C_4H_{10}\xrightarrow{t^o,xt}C_3H_6+CH_4$
$C_3H_6+H_2\xrightarrow{t^o,Ni}C_3H_8$
