Hint: The Kolbe Electrolysis is the electrochemical oxidative decarboxylation of carboxylic acids leasing to the formation of the radicals that dimerise resulting in the formation of an alkene molecule.Complete step-by-step answer:When a solution of 2, 3-dimethyl maleic acid is hydrolysed then it leads to the formation of but-2-ene. The carboxylate anion releases two electrons and it results in the formation of the carboxylic radical and then two molecules of carbon dioxide then it forms but-2-ene. There are certain side-products that are formed along with the products in the reaction. The reaction mechanism can be represented as follows:

Hence, the correct answer is option A.Note: The Kolbe reaction is named after Hermann Kolbe. The Kolbe reaction is formally a decarboxylative dimerization of two carboxylate anions or acids.

The carboxylic acids can be formed from the alkenes by the oxidation using different oxidising agents such as osmium tetroxide and potassium permanganate and potassium dichromate. Ozonolysis is yet another route for the preparation of acids from alkenes.

The reaction of carbon dioxide with Grignard’s reagent also gives rise to carboxylic acids.

In the haloform reaction with iodine, bromine, and chlorine, methyl ketones are converted to the corresponding haloalkanes and the carboxylic acids.
