Which of the following change represents a disproportionation reaction (s) :

Options

A. `Cl_(2)+2OH^(-) to ClO^(-)+Cl^(-)+H_(2)O`
B. `Cu_(2)O+2H^(+) to Cu+Cu^(+2) + H_(2)O`
C. `2HCuCl_(2)underset("water") overset("dilution with")to Cu+Cu^(+2) +4Cl^(-) + 2H^(+)`
D. All the above

Answer

D

Explanation

All the three are disproportionation reactions. It is reaction in which oxidising and reducing agents are same.
