Electrolysis

Vedclass · Answer

(D) The preparation of alkenes from the sodium or potassium salts of carboxylic acids is known as $Kolbe's$ electrolysis. In this process,an aqueous concentrated solution of the salt is subjected to electrolysis. At the anode,the carboxylate ion loses an electron to form a radical,which then loses $CO_2$ to form an alkyl radical. Two alkyl radicals combine to form an alkene (or alkane depending on the starting material). Thus,the correct process is electrolysis.
