$2CH_4\xrightarrow{{1500^oC}} C_2H_2+3H_2$

$C_2H_2+H_2\xrightarrow{{Pd/PbCO_3, t^o}} C_2H_4$

$C_2H_4+HCl\to C_2H_5Cl$

$C_2H_5Cl+NaOH\xrightarrow{{t^o}} C_2H_5OH+NaCl$

$C_2H_5OH+CuO\xrightarrow{{t^o}} CH_3CHO+Cu+H_2O$

$CH_3CHO+Br_2+H_2O\to CH_3COOH+2HBr$

2.

$Al_4C_3+12H_2O\to 4Al(OH)_3+3CH_4$

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

$C_6H_6+CH_3Cl\xrightarrow{{AlCl_3, t^o}} C_6H_5CH_3+HCl$

$C_6H_5CH_3+Br_2\xrightarrow{{Fe, t^o}} HBr+o-C_6H_4BrCH_3$

$o-BrC_6H_4CH_3+2KMnO_4\xrightarrow{{t^o}}o-BrC_6H_4COOK+2MnO_2+KOH+H_2O$

$o-BrC_6H_4COOK+HCl\to KCl+o-BrC_6H_4COOH$ (axit ortho-brombenzoic)
