Expected Weightage
The Common University Entrance Test (CUET) for Chemistry includes Redox Reactions as an important topic under Unit II: Solutions. Analyzing the last 3 years’ (2022-2024) marking patterns and chapter-wise weightage helps in strategic preparation.
1. Redox Reactions: Chapter-wise Weightage (CUET UG Chemistry)
- Unit II: Solutions (includes Redox Reactions) typically carries ~10-15% weightage in the Chemistry section.
- Redox Reactions alone contributes ~5-8 marks per year (varies slightly).
Year-wise Breakdown:
| Year | Total Marks (Chemistry) | Redox Reactions Marks | Weightage (%) |
|---|---|---|---|
| 2024 | 50 (expected) | 6-8 | 12-16% |
| 2023 | 50 | 5-7 | 10-14% |
| 2022 | 50 | 4-6 | 8-12% |
2. Types of Questions Asked (Last 3 Years)
-
MCQs (1 mark each) :
-
Balancing redox reactions (acidic/alkaline medium).
-
Identifying oxidizing/reducing agents.
-
Calculating oxidation states.
-
Nernst equation applications.
-
Electrochemical cells (E°cell calculations).
-
Assertion-Reasoning (1-2 questions)
-
Based on redox concepts and applications.
3. Important Topics (High Frequency)
| Topic | Marks (Avg.) | Remarks |
|---|---|---|
| Oxidation States | 1-2 | Common in all years |
| Balancing Redox Reactions | 2-3 | Mostly acidic/alkaline medium |
| Electrochemical Cells | 1-2 | Nernst equation, E°cell |
| Oxidizing/Reducing Agents | 1 | Identification-based |
| Applications (Corrosion, Batteries) | 1 | Conceptual |
4. Trends Predictions for 2025
- Balancing reactions and Nernst equation remain highly frequent.
- Assertion-Reasoning questions may increase.
- Direct formula-based (E°cell) questions are common.
5. Preparation Tips
✔ Focus on NCERT (Class 11 12) – Covers 90% of CUET questions. ✔ Practice balancing redox reactions (acidic/alkaline medium). ✔ Memorize common oxidizing/reducing agents. ✔ Solve previous years’ papers (2022-2024).
Conclusion
- Redox Reactions consistently contribute 5-8 marks in CUET Chemistry.
- Balancing reactions electrochemical cells are must-practice topics.
- Weightage is stable (~10-15%) , so allocate study time accordingly.
