Vedclass · Answer

(A) In Kolbe's electrolysis of sodium salt of carboxylic acid $(RCOO^{-}Na^{+})$,the reaction occurs as follows:At the anode,the carboxylate ion $(RCOO^{-})$ loses an electron to form an acyloxy radical $(RCOO^{\bullet})$,which then decarboxylates to form an alkyl radical $(R^{\bullet})$.At the cathode,water molecules undergo reduction to produce hydrogen gas and hydroxide ions,involving the formation of hydrogen radicals $(H^{\bullet})$ as intermediates during the electron transfer process.Therefore,the free radicals obtained are $R^{\bullet}$ at the anode and $H^{\bullet}$ at the cathode.

Which free radicals are obtained on anode and cathode during electrolysis of $RCOO^{-}Na^{+}$ in Kolbe's electrolysis?
