Vedclass · Answer

(A) $Cu^{2+}(aq.)$ acts as an oxidizing agent.It oxidizes $I^{-}(aq.)$,$CN^{-}(aq.)$,and $SCN^{-}(aq.)$ to their respective products $I_2$,$(CN)_2$,and $(SCN)_2$ while getting reduced to $CuX$.However,$Cl^{-}(aq.)$ is a much weaker reducing agent compared to the others and cannot be oxidized by $Cu^{2+}(aq.)$ at room temperature $(R.T.)$.Therefore,$X$ cannot be $Cl^{-}(aq.)$.

$Cu^{2+}(aq.) + X^{-}(aq.) \xrightarrow{R.T.} CuX \downarrow + X_2$
$X$ cannot be
