Vedclass · Answer

(C) In the reaction $Cu^{2+} (aq.) + 2I^{-} \longrightarrow CuI \downarrow + \frac{1}{2}I_2$,the oxidation state of $Cu$ changes from $+2$ to $+1$ (reduction).The oxidation state of $I$ changes from $-1$ to $0$ (oxidation).Since two different species are being oxidized and reduced in an intermolecular process,this is an intermolecular redox reaction.Also,it can be classified as a displacement reaction where $I^-$ displaces $Cu^{2+}$ to form $CuI$.Therefore,the correct classification is $C$.

Assign $A$,$B$,$C$,$D$ from the given type of reaction.
$Cu^{2+} (aq.) + 2I^{-} \longrightarrow CuI \downarrow + \frac{1}{2}I_2$
