Solution

(A) Hydrogen reacts with carbon monoxide in presence of cobalt catalyst to give methanol <br/><br/> $$ 2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{CO}(\mathrm{g}) \stackrel{\text { cobalt catalyst }}{\longrightarrow} \mathrm{CH}_{3} \mathrm{OH}(\mathrm{I}) $$ <br/><br/> (B) Syn gas is produced from coal and the process is called coal gasification. <br/><br/> $$ \mathrm{C}(\mathrm{s})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \stackrel{1270 \mathrm{~K}}{\longrightarrow} \underset{(\text { syn gas) }}{\mathrm{CO}(\mathrm{g})+\mathrm{H}_{2}(\mathrm{~g})} $$ <br/><br/> (C) Reaction of steam with hydrocarbons or coke at high temperature in presence of nickel catalyst gives a mixture of $\mathrm{CO}$ and $\mathrm{H}_{2}$, called water gas <br/><br/> $$ \mathrm{CH}_{4}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \underset{{\mathrm{Ni}}}{\stackrel{1270 \mathrm{~K}}{\longrightarrow}}\underset{(\text { water gas })}{\mathrm{CO}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{~g})} $$<br/><br/> (D) Electrolysis of brine solution produces $\mathrm{H}_{2}$ gas at cathode and $\mathrm{Cl}_{2}$ gas at anode <br/><br/> $\mathrm{NaCl}(\mathrm{aq}) \longrightarrow \mathrm{Na}^{+}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq})$ <br/><br/> Cathode : $2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l})+2 \mathrm{e}^{-} \longrightarrow \mathrm{H}_{2}(\mathrm{~g})+2 \mathrm{OH}^{-}(\mathrm{aq})$ <br/><br/> Anode : $2 \mathrm{Cl}^{-}(\mathrm{aq}) \longrightarrow \mathrm{Cl}_{2}(\mathrm{~g})+2 \mathrm{e}^{-}$
