Answer 1

a)

\(4Al+3C\xrightarrow[]{1500-1700^oC}Al_4C_3\\ Al_4C_3+12H_2O\rightarrow4Al\left(OH\right)_3\downarrow+3CH_4\uparrow\\ CH_4+Cl_2\xrightarrow[]{a/s}CH_3Cl+HCl\\ CH_3Cl+Cl_2\xrightarrow[]{a/s}CH_2Cl_2+HCl\\ CH_2Cl_2+Cl_2\xrightarrow[]{a/s}CHCl_3\\ CHCl_3+Cl_2\xrightarrow[]{a/s}CCl_4+HCl\)

b)

\(CH_3COOH+NaOH\rightarrow CH_3COONa+H_2O\\ CH_3COONa+NaOH\xrightarrow[]{CaO,t^o}CH_4\uparrow+Na_2CO_3\)

\(CH_4+Cl_2\xrightarrow[]{a/s}CH_3Cl+HCl\\ 2CH_3Cl+2Na\xrightarrow[]{t^o}2NaCl+C_2H_6\\ C_2H_6\xrightarrow[]{t^o,xt}C_2H_4\)

c)

\(C_4H_{10}\xrightarrow[]{crackinh}C_2H_6+C_2H_4\\ C_2H_6+Cl_2\xrightarrow[]{a/s}C_2H_5Cl+HCl\\ 2C_2H_5Cl+2Na\xrightarrow[]{t^o,xt}C_4H_{10}+2NaCl\\ C_4H_{10}\xrightarrow[]{crackinh}CH_4+C_3H_6\\ C_3H_6+H_2\xrightarrow[]{Ni,t^o}C_3H_8\)
