Expected Weightage
The Common University Entrance Test (CUET) for Chemistry, particularly the Atomic Structure chapter, has shown some trends in terms of marking pattern and weightage over the last few years (2022–2024). Below is a detailed analysis based on available data and trends:
1. CUET Chemistry Marking Pattern (General)
- Total Questions in Chemistry Section: ~50 (out of which ~40 need to be attempted)
- Marks per Question: +5 for correct, -1 for incorrect, 0 for unattempted
- Total Marks (Chemistry): ~200 (40 × 5)
2. Atomic Structure Chapter Weightage (Last 3 Years)
| Year | No. of Questions | Approx. Weightage (%) | Marks Allocated |
|---|---|---|---|
| 2024 | 3–4 | 7.5–10% | 15–20 |
| 2023 | 2–3 | 5–7.5% | 10–15 |
| 2022 | 2–4 | 5–10% | 10–20 |
Key Observations:
- Increasing Weightage: The chapter has gained slightly more importance in 2024 compared to 2022–2023.
- Consistent Topics: Questions frequently appear from:
- Bohr’s atomic model
- Quantum numbers orbitals
- Electronic configuration
- Heisenberg’s uncertainty principle
- De Broglie’s equation
3. Comparative Weightage with Other Chapters
| Chapter | Weightage (2024) | Weightage (2023) | Weightage (2022) |
|---|---|---|---|
| Atomic Structure | 7.5–10% | 5–7.5% | 5–10% |
| Chemical Bonding | 10–12% | 10–15% | 8–12% |
| Thermodynamics | 8–10% | 7–10% | 7–10% |
| Organic Chemistry | 20–25% | 20–25% | 18–22% |
| Electrochemistry | 5–8% | 5–7% | 5–8% |
Analysis:
- Atomic Structure is mid-weightage (~5–10%), less than Organic Chemistry but more than Electrochemistry.
- 2024 saw a slight increase in questions from Atomic Structure compared to previous years.
4. Expected Topics Difficulty Level
- Most Repeated Topics:
- Quantum numbers (n, l, m, s)
- Pauli’s exclusion principle
- Aufbau principle exceptions
- Photoelectric effect (Einstein’s equation)
- Difficulty Level: Mostly moderate , with 1–2 tricky questions (e.g., conceptual clarity on orbitals).
5. Preparation Strategy
- Focus Areas:
- Bohr’s model limitations
- Quantum mechanical model (Schrödinger’s equation)
- Electronic configuration of ions (Cr, Cu, etc.)
- Practice Numerical Problems:
- De Broglie wavelength
- Heisenberg’s uncertainty principle
- Previous Year Questions (PYQs): Solve CUET 2022–2024 questions for trends.
Conclusion
- Atomic Structure holds ~5–10% weightage in CUET Chemistry.
- 2024 had a slight increase in questions (~3–4) compared to 2022–2023 (~2–3).
- Organic Chemistry Chemical Bonding still dominate, but Atomic Structure remains crucial for scoring.
