Vedclass · Answer

(A) The homologous series of alkanes is represented by the general formula $C_n H_{2n+2}$.Methane is $CH_4$ $(n=1)$.The next member in the homologous series is ethane,$C_2 H_6$ $(n=2)$.$I$. Wurtz reaction: $2 CH_3 Br \xrightarrow[	ext{dry ether}]{Na} CH_3-CH_3 + 2 NaBr$. This produces ethane.$II$. Decarboxylation: $CH_3 COONa \xrightarrow[CaO, \Delta]{NaOH} CH_4 + Na_2 CO_3$. This produces methane.$III$. Hydrogenation: $CH_3-CH=CH_2 \xrightarrow{H_2 / Pt} CH_3-CH_2-CH_3$. This produces propane.$IV$. Reduction of alkyl halide: $CH_3-CH_2 Br \xrightarrow[H^{+}]{Zn} CH_3-CH_3 + HBr$. This produces ethane.Therefore,reactions $I$ and $IV$ produce ethane.
