Assertion (A): H₂O₂ can acts as an oxidizing agent. Reason (R): All the peroxides behave as oxidizing agents only.

A.If both (A) and (R) are correct and (R) is the correct

B.If both (A) and (R) are correct but (R) is not the

C.If (A) is correct but (R) is incorrect.✓ Correct

D.If (A) is incorrect but (R) is correct

Explanation

H₂O₂ acts both as an oxidizing and a reducing agent. 2 2 2 H O O 2H 2e → (Oxidation; acts as a reducing agent) 2 2 2 2e 2H H O 2H O → (Reduction; acts as oxidising agent) All peroxides can act either as an oxidizing agent or as a reducing agent or both.
