Vedclass · Answer

(A) In the Gattermann reaction,the diazonium group $(-N_2^+Cl^-)$ is replaced by a halogen atom (like $Cl$ or $Br$) using copper powder $(Cu)$ in the presence of the corresponding halogen acid ($HCl$ or $HBr$).Specifically,the diazonium cation is attacked by the nucleophilic halide ion $(Cl^{\ominus})$ generated in the reaction mixture,facilitated by the copper catalyst.Therefore,$\underline{X}$ is $Cl^{\ominus}$ and $\underline{Y}$ is $Cu / HCl$.

In Gattermann reaction,a diazonium group is replaced by $\underline{X}$ using $\underline{Y}$. $\underline{X}$ and $\underline{Y}$ are:
$\underline{X} \quad \underline{Y}$
