Vedclass · Answer

(D) Step $A$: The conversion of nitrobenzene $(C_6H_5NO_2)$ to aniline $(C_6H_5NH_2)$ is a reduction reaction,which is achieved using $Sn / HCl$ or $Fe / HCl$.Step $B$: The conversion of aniline $(C_6H_5NH_2)$ to benzene diazonium chloride $(C_6H_5N_2^+Cl^-)$ is a diazotization reaction,which is achieved using $NaNO_2 / HCl$ at $0-5 \ ^\circ C$.Step $C$: The conversion of benzene diazonium chloride $(C_6H_5N_2^+Cl^-)$ to benzene $(C_6H_6)$ is a reduction reaction,which is achieved using ethanol $(CH_3CH_2OH)$ or hypophosphorous acid $(H_3PO_2)$.Therefore,the reagents are $A = Sn / HCl$,$B = NaNO_2 / HCl$,and $C = CH_3CH_2OH$.

Identify the reagents $A, B, C$ respectively in the following reaction sequence:
