Vedclass · Answer

(A) The electrolysis of aqueous potassium maleate (cis-butenedioate) is an example of the Kolbe electrolysis reaction. During electrolysis,the maleate ion undergoes decarboxylation at the anode to form an alkyne. The reaction is as follows: $cis-KOOC-CH=CH-COOK \xrightarrow{electrolysis} HC \equiv CH + 2CO_2 + H_2 + 2KOH$. Thus,the product formed is acetylene $(CH \equiv CH)$.

The electrolysis of aqueous potassium maleate gives which of the following products?
