Which of the following compound cannot be oxidised by
Which of the following compound cannot be oxidised by \( \boldsymbol{O}_{3} ? \)
- A. \( K I \)
- B. \( K M n O_{4} \)
- C. \( K_{2} \) Мп \( O_{4} \)
- D. \( F e S O_{4} \)
Step-by-step solution
KMnO4 contains manganese in its highest oxidation state (+7), so it cannot be further oxidized. Ozone (O3) is a strong oxidizing agent but cannot oxidize Mn from +7 to a higher state. In contrast, KI (I- to I2), K2MnO4 (Mn+6 to Mn+7), and FeSO4 (Fe2+ to Fe3+) can be oxidized by O3.
