Vedclass · Answer

(C) The reaction involves the nucleophilic substitution of a primary alkyl bromide with $CN^-$ in a non-polar solvent (benzene). Since $KCN$ is ionic and insoluble in non-polar solvents like benzene,a phase transfer catalyst is required to transport the $CN^-$ ion into the organic phase. Quaternary ammonium salts,such as benzyltrimethylammonium chloride $(C_6H_5CH_2N^+(CH_3)_3Cl^-)$,act as effective phase transfer catalysts because they have both a lipophilic part (to dissolve in benzene) and a cationic part (to associate with the $CN^-$ anion). Therefore,option $C$ is the correct catalyst.
