- Negative Marking: -1 for incorrect answers
- Duration: 45 minutes
2. Chapter-wise Weightage (Trend Analysis)
The syllabus is based on Class 12 NCERT Chemistry (Unit 14: Environmental Chemistry). The weightage varies slightly each year, but key topics remain consistent.
2023 Analysis
| Chapter/Topic | Weightage (%) | Approx. No. of Questions |
|---|---|---|
| Environmental Pollution | 30–35% | 15–17 |

| Soil Pollution Waste Mgmt | 10–15% | 5–7 |
| Acid Rain Smog | 10–15% | 5–7 |
| Miscellaneous (Green Chemistry, etc.) | 5–10% | 2–4 |
2022 Analysis
- Highest Weightage: Environmental Pollution (~30%)
- Moderate Focus: Greenhouse Effect (20%), Water Pollution (15%)
- Least Asked: Green Chemistry (~5%)
2021 Analysis
- Dominant Topics: Air Pollution (25%), Ozone Depletion (20%)
- Emerging Focus: Waste Management (10–12%)
3. Key Observations
- Environmental Pollution (Air, Water, Soil) consistently holds 30–35% weightage.
- Greenhouse Effect Ozone Layer are recurring themes (~20–25%).
- Application-based questions (e.g., treatment methods, case studies) are increasing.
- NCERT Focus: 90% of questions are directly from NCERT Class 12 (Unit 14).
4. Preparation Tips
✔ Priority Chapters: Pollution, Greenhouse Effect, Water Treatment. ✔ NCERT + PYQs: Solve past papers (2021–2023) for pattern familiarity. ✔ Diagrams Case Studies: Expect questions on real-world applications (e.g., Ganga Action Plan).
