(A) In the Gattermann reaction,the diazonium group $(-N_2^+Cl^-)$ is replaced by a chlorine atom $(-Cl)$ using copper powder $(Cu)$ in the presence of hydrochloric acid $(HCl)$.Specifically,the nucleophilic species involved in the substitution is the chloride ion $(Cl^{\ominus})$,and the reagents used are $Cu$ powder and $HCl$.Therefore,$\underline{X} = Cl^{\ominus}$ and $\underline{Y} = Cu / HCl$.
