2. Giải thích các bước giải:

   15.

   $C_4H_{10}\xrightarrow{t^o,xt}C_2H_4↑+C_2H_6↑$

   $C_2H_6+Cl_2\xrightarrow{As}C_2H_5Cl+HCl$

   16.

   $CH_3COONa+NaOH\xrightarrow{t^o,CaO}Na_2CO_3+CH_4↑$

   $CH_4+Cl_2\xrightarrow{As}CH_3Cl+HCl$

   $CH_3Cl+Cl_2\xrightarrow{As}CH_2Cl_2+HCl$

   $CH_2Cl_2+Cl_2\xrightarrow{As}CHCl_3+HCl$

   $CHCl_3+Cl_2\xrightarrow{As}CCl_4+HCl$
