Which type of reaction occurs in Kolbe's electrolysis? Why?
(N/A) Kolbe's electrolysis is a $redox$ reaction.
At the anode,the carboxylate ion undergoes de-electronation (oxidation) to form an alkyl radical,which then dimerizes to form an alkane.
At the cathode,the water molecules or protons undergo electronation (reduction) to release $H_2$ gas.
