(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.
