Vedclass · Answer

(A) The reaction $2 Cu^{2+} + 4 X^{-} \rightarrow Cu_2 X_{2(s)} + X_2$ represents the reduction of $Cu^{2+}$ to $Cu^+$ by halide ions.This reaction occurs specifically with iodide ions $(I^-)$ because $CuI_2$ is unstable and decomposes to form $Cu_2I_2$ and $I_2$.Chlorine and bromine are not strong enough reducing agents to reduce $Cu^{2+}$ to $Cu^+$ under these conditions.Therefore,the correct answer is $I^-$ (Iodine).

$2 Cu^{2+} + 4 X^{-} \rightarrow Cu_2 X_{2(s)} + X_2$
