Match the compounds in Column I with the term(s) in Column II.
Column I | Column II |
|---|---|
A) SO₂ | P) Oxidizing agent |
B) SO₃ | Q) Reducing agent |
C) H₂O₂ | R) Undergoes disproportionation in air |
D) NaF | S) Neither an oxidizing nor a reducing agent |
Options:
Answer:
C
Solution:
(A) S in SO₂ is +4 (intermediate between -2 and +6), so SO₂ can be oxidized or reduced: both oxidizing and reducing agent (P, Q). (B) S in SO₃ is +6, its maximum, so it can only be reduced: oxidizing agent only (P). (C) O in H₂O₂ is -1 (intermediate), so it acts as oxidant and reductant, and 2H₂O₂ 2H₂O + O₂ is disproportionation in air (P, Q, R). (D) Na⁺ is not reduced in ordinary chemistry and F⁻ (F at -1, its minimum) resists oxidation: neither (S).
