Question Style in MHT CET Redox Reactions PYQs
Every question in this PDF is a single-correct MCQ. More than half ask for an oxidation state or number, and the rest ask about electrons, agents or whether a reaction is redox.
| Question Style | What it Tests |
|---|---|
| Oxidation state | The oxidation state of Xe in XeOF₄, of Cl in HOClO, of Cl in chlorous acid, of Cr in CrO₄²⁻ and Cr₂O₇²⁻, and of I in I₂Cl₆ |
| Oxidation state of oxygen | The oxidation state of oxygen in OF₂ and in KO₂ |
| Electrons transferred | The electrons transferred when KMnO₄ is converted to Mn₂O₃, the electrons released in the conversion of C₂O₄²⁻ to CO₂, and the value of x in BiO₃⁻ + 6H⁺ + xe⁻ → Bi³⁺ + 3H₂O |
| Agents and elements reduced | The element reduced in Cr₂O₇²⁻ + 14H⁺ + 6I⁻ → 2Cr³⁺ + 3H₂O + 3I₂, and the change in oxidation state of the oxidising agent in a reaction of H₃AsO₃ |
| Is it redox | Which of the given reactions is, or is NOT, a redox reaction, and which oxide can act both as an oxidising and as a reducing agent |
How to Use the Redox Reactions PYQ PDF for MHT CET
- Start with the 2025 and 2026 papers first, because they hold 33 of the 71 questions.
- Learn the fixed oxidation states, such as +1 for hydrogen, -2 for oxygen except in peroxides, and -1 for the halogens in halides, and then solve for the unknown element.
- For electron counts, write the oxidation state before and after and take the difference for each atom.
- 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.
