Vedclass · Answer

(D) Methane $(CH_4)$ can be prepared by the following methods:$1$. Decarboxylation: Heating sodium acetate $(CH_3COONa)$ with soda lime $(NaOH + CaO)$ yields methane $(CH_3COONa + NaOH \xrightarrow{\Delta, CaO} CH_4 + Na_2CO_3)$.$2$. Hydrogenation: Catalytic hydrogenation of carbon monoxide $(CO + 3H_2 \xrightarrow{Ni, 573K} CH_4 + H_2O)$.$3$. Wurtz reaction: While Wurtz reaction is typically used for higher alkanes,it can produce methane if methyl halides are reacted with sodium in the presence of a suitable catalyst or specific conditions,though it is less common for methane specifically. However,since decarboxylation and hydrogenation are standard methods for methane,and the question asks for preparation methods,'All of the above' is the most appropriate choice.
