The acid whose sodium salt on electrolysis gives acetylene is
Open in App
Solution
The correct option is A Fumaric acid
Kolbe's electrolysis is a preparation method for alkynes. Here, the alkene dicarboxylate potassium/sodium salts are electrolysed in water to give respective alkynes. During electrolysis the carboxylate group breaks and remove as CO2 leaving free radicals. Then the radicals combine to form the alkyne compounds. The potassium ions in solution combine with OH− to give KOH. Thus, the solution left after electrolysis is basic in nature.
When an aqueous solution of ‘Na’/’K’ salts of fumaric acid and maleic acid on electrolysis gives ethyne at the anode.
