The compounds formed at anode in the electrolysis of an aqueous solution of potassium acetate, are

The compounds formed at anode in the electrolysis of an aqueous solution of potassium acetate, are

Options

A $\mathrm{C}_2 \mathrm{H}_6$ and $\mathrm{CO}_2$
B $\mathrm{C}_2 \mathrm{H}_4$ and $\mathrm{CO}_2$
C $\mathrm{CH}_4$ and $\mathrm{H}_2$
D $\mathrm{CH}_4$ and $\mathrm{CO}_2$

Correct answer

A. $\mathrm{C}_2 \mathrm{H}_6$ and $\mathrm{CO}_2$

Step-by-step solution

This is an example of Kolbe's electrolysis.

2 \mathrm{CH}_3 \mathrm{COOK} \xrightarrow{\text{ electrolysis }} 2 \mathrm{CH}_3 \mathrm{COO}^{-}+2

\mathrm{~K}^{+}

At cathode :

\begin{array}{r} 2 \mathrm{~K}^{+}+2 e^{-} \longrightarrow 2 \mathrm{~K} \\ 2 \mathrm{~K}+2 \mathrm{H}_2 \mathrm{O} \longrightarrow 2 \mathrm{KOH}+\mathrm{H}_2 \uparrow \end{array}

At anode : The compounds formed at anode in the electrolysis of an aqueous solution of potassium acetate, are

The compounds formed at anode in the electrolysis of an aqueous solution of potassium acetate, are
