Question

Assertion (A) The decomposition of hydrogen peroxide to form water and oxygen is an example of disproportionation reaction.
Reason (R) The oxygen of peroxide is in $-1$ oxidation state and it is converted to zero oxidation state in $O _{2}$ and $-2$ oxidation state in $H _{2} O$.

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$.
• C. $A$ is correct; $R$ is incorrect.
• D. $A$ is incorrect; $R$ is correct.

Answer 1

Answer: (A)

Thus, the above reaction is an example of disproportionation reaction.
Thus, both $A$ and $R$ are correct and $R$ is the correct explanation of $A$.
