Vedclass · Answer

(B) In reaction $(I)$,benzene reacts with $CO$ and $HCl$ in the presence of anhydrous $AlCl_3/CuCl$ to form benzaldehyde (Gattermann-Koch reaction). No carboxylate ion is formed.In reaction $(II)$,acetaldehyde $(CH_3CHO)$ reacts with Tollen's reagent $([Ag(NH_3)_2]^+)$ in a basic medium to form an acetate ion $(CH_3COO^-)$,which is a carboxylate ion.In reaction $(III)$,benzaldehyde reacts with Fehling's solution $(Cu^{2+}/OH^-)$ to form a benzoate ion $(C_6H_5COO^-)$,which is a carboxylate ion.In reaction $(IV)$,aniline is treated with $Cl_2/hv$ followed by $H_2O$ at $373 \ K$,which does not produce a carboxylate ion.Therefore,reactions $(II)$ and $(III)$ produce a carboxylate ion in their reaction mixture.

Which of the following reactions gives a carboxylate ion in their reaction mixture?
