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 \[\ce{O2}\] and –2 oxidation state in \[\ce{H2O}\].
Options
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
Both A and R are false.
Solution
Both A and R are true and R is the correct explanation of A.
Explanation:
Here the oxygen of peroxide, which is present in –1 state, is converted to zero oxidation state in \[\ce{O2}\] undergoing oxidation and decreases to –2 oxidation state in \[\ce{H2O}\] undergoing reduction.
