Question

An example of disproportionation reaction is :

• A. \( 2H_2O_2 \rightarrow 2H_2O + O_2 \)
• B. \( 2KMnO_4 \rightarrow K_2MnO_4 + MnO_2 + O_2 \)
• C. \( 2MnO_4^- + 10I^- + 16H^+ \rightarrow 2Mn^{2+} + 5I_2 + 8H_2O \)
• D. \( 2NaI + Cl_2 \rightarrow 2NaCl + I_2 \)

Hint:

In disproportionation reactions, always check if the same element is getting oxidized and reduced simultaneously by comparing oxidation states before and after the reaction.
