In disproportionation, the element in the reacting substance is in a state that is:
AUndefined
BIntermediate
CThe highest
DThe lowest
Answer & Solution
Correct answer: B. Intermediate
1. The element needs room to move in both directions.
2. It cannot be at either end of its range.
3. So it starts in the intermediate oxidation state.
