NEET levelSingle correct optionDifficulty 1 of 3co175

A concentrated aqueous solution of sodium ethanoate is electrolysed. The main organic product formed at the anode is

A $CH X_{3} OH$
B $C X_{4} H X_{10}$
C $CH X_{4}$
D $C X_{2} H X_{6}$

Answer: D

In Kolbe electrolysis the carboxylate is oxidised at the anode to

CH X_{3} COO \cdot

, which loses

CO X_{2}

to give

CH X_{3} \cdot

. Two methyl radicals combine to give ethane (along with

CO X_{2}

).
