Question

Quizplus · Accepted Answer

In a disproportionation reaction, a single element is simultaneously oxidized and reduced. In option C, the element in question is H, which goes from -1 in H2O2 to 0 in O2 and -2 in H2O. Therefore, option C is the only answer choice that fits the definition of a disproportionation reaction.
