(D) The electrolysis of a mixture of sodium salts of carboxylic acids is known as the Kolbe electrolysis reaction.
For a mixture of sodium acetate $(CH_3COONa)$ and sodium propionate $(CH_3CH_2COONa)$,the following reactions occur at the anode:
$1$. $CH_3COO^-$ $\rightarrow CH_3COO^{\bullet} + e^-$ $\rightarrow CH_3^{\bullet} + CO_2$
$2$. $CH_3CH_2COO^-$ $\rightarrow CH_3CH_2COO^{\bullet} + e^-$ $\rightarrow CH_3CH_2^{\bullet} + CO_2$
The free radicals formed ($CH_3^{\bullet}$ and $CH_3CH_2^{\bullet}$) combine in three possible ways:
- $CH_3^{\bullet} + CH_3^{\bullet} \rightarrow CH_3-CH_3$ (Ethane)
- $CH_3CH_2^{\bullet} + CH_3CH_2^{\bullet} \rightarrow CH_3CH_2-CH_2CH_3$ (Butane)
- $CH_3^{\bullet} + CH_3CH_2^{\bullet} \rightarrow CH_3-CH_2CH_3$ (Propane)
Thus,the mixture of products obtained is Ethane,Propane,and Butane.

Column-$I$	Column-$II$
$i$. $n$-Butane $\to 2$-methylpropane	$A$. Free radical substitution
$ii$. $CH_4 + Cl_2 \xrightarrow{hv} CH_3Cl + HCl$	$B$. Wurtz reaction
$iii$. $R-COONa \xrightarrow{\text{soda-lime}} R-H$	$C$. Isomerism
$iv$. $R-X + Na \xrightarrow{\text{Ether}} R-R$	$D$. Decarboxylation
