  • question_answer 71)   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 sate in \[{{O}_{2}}\] and -2 oxidation state in\[{{H}_{2}}O\]. (a) Both A and R are true and R is the correct explanation of the A. (b)Both A and R are true but R is not the correct explanation of the A. (c) A is true but R is false. (d) Both A and R are false.
