Question Style in MHT CET Oxidation and Reduction Reactions PYQs
Every question in this PDF is a single-correct MCQ. Most give a reaction and ask which substance is oxidised, reduced or the reductant.
| Question Style | What it Tests |
|---|---|
| Reductant | The reducing agent in H₂O₂ + ClO₂⁻ → ClO₄⁻ + O₂, in H₂S + NO₂ → H₂O + NO + S, and in the oxalate and permanganate reaction |
| Element reduced | The element reduced in Cr₂O₇²⁻ + 14H⁺ + 6I⁻ → 2Cr³⁺ + 3H₂O + 3I₂, and the elements oxidised and reduced in a reaction of H₃AsO₃ |
| Is it redox | Which of the given is a redox reaction, which is NOT a redox reaction, and which conversion involves neither oxidation nor reduction |
| Electrons transferred | The number of electrons transferred when KMnO₄ is converted to Mn₂O₃ |
| Dual behaviour | The oxide that can act both as an oxidising agent and as a reducing agent |
How to Use the Oxidation and Reduction Reactions PYQ PDF for MHT CET
- Start with the 2025 and 2026 papers first, because they hold 7 of the 17 questions.
- Write the oxidation number of every element on both sides, since the change shows what is oxidised or reduced.
- Remember that the reductant is the species that loses electrons and so is oxidised.
- Solve year-wise PYQs by timing yourself, as time management is crucial.
- Re-attempt only the questions you got wrong, and note which formula or step you missed.
