Vedclass · Answer

(C) The reaction of aniline with $NaNO_2$ and $HCl$ at $278 \ K$ $(0-5 \ ^\circ C)$ is known as diazotization,which produces benzene diazonium chloride $(A)$.Reaction: $C_6H_5NH_2 + NaNO_2 + 2HCl \xrightarrow{278 \ K} C_6H_5N_2^+Cl^- + NaCl + 2H_2O$.When benzene diazonium chloride $(A)$ is treated with fluoroboric acid $(HBF_4)$,it forms benzene diazonium fluoroborate,which upon heating decomposes to give fluorobenzene $(B)$.Reaction: $C_6H_5N_2^+Cl^- + HBF_4$ $\rightarrow C_6H_5N_2^+BF_4^- + HCl$ $\xrightarrow{\Delta} C_6H_5F + N_2 + BF_3$.Thus,$A$ is benzene diazonium chloride and $B$ is fluorobenzene.

In the chemical reactions,the compounds $A$ and $B$ respectively are
