Question

Which of the following is not an intramolecular redox reaction ?

• A. $\text{NH}_{4} \text{NO}_{2} \rightarrow \text{N}_{2} + 2 \text{H}_{2} \text{O}$
• B. $2 \text{Mn}_{2} \text{O}_{7} \rightarrow 4 \text{MnO}_{2} + 3 \text{O}_{2}$
• C. $2 \text{KClO}_{3} \rightarrow 2 \text{KCl} + 3 \text{O}_{2}$
• D. $2 \text{H}_{2} \text{O}_{2} \rightarrow 2 \text{H}_{2} \text{O} + \text{O}_{2}$

Answer 1

Answer: (D)

The given reaction is intermolecular reaction .
In intramolecular redox reaction, the molecule of a single substance undergoes oxidation-reaction by the process decomposition.
