a) CH4 \(\overset{1500^{\circ}}{\rightarrow}\)C2H2 \(\overset{+ H_{2}, Pd,t^{\circ}}{\rightarrow}\) C2H4 \(\overset{+H_{2}O,H^{+},t^{\circ}}{\rightarrow}\) C2H5OH \(\overset{+O_{2},men}{\rightarrow}\) CH3COOH
(1) 2CH4 \(\overset{1500^{\circ}}{\rightarrow}\) C2H2 + 3H2
(2) C2H2 + H2 \(\overset{Pd,t^{\circ}}{\rightarrow}\) C2H4
(3) C2H4 + H2O \(\overset{H^{+},t^{\circ}}{\rightarrow}\) C2H5OH
(4) 2C2H5OH + O2 \(\overset{men}{\rightarrow}\) 2CH3COOH
b) C6H6 \(\overset{+Br_{2}/Fe}{\rightarrow}\) C6H5Br \(\overset{NaOH}{\rightarrow}\) C6H5ONa \(\overset{+CO_{2}, H_{2}O}{\rightarrow}\) C6H5OH \(\overset{+ Br_{2}}{\rightarrow}\) Br3C6H2OH
(1) C6H6 + Br2 \(\overset{Fe}{\rightarrow}\) C6H5Br
(2) C6H5Br \(\overset{NaOH}{\rightarrow}\) C6H5ONa + HBr
(3) C6H5ONa + CO2 + H2O → C6H5OH + NaHCO3
(4)
