How to prepare for Organic Chemistry Basics for CUET-UG ?
Expected Weightage
The Common University Entrance Test (CUET) for Organic Chemistry Basics has shown consistent trends in its marking pattern and chapter-wise weightage over the last three years (2022–2024). Below is a detailed analysis based on past papers and expert reviews.
1. Overall Weightage of Organic Chemistry in CUET
- Total Marks (Chemistry Section): ~50 (varies slightly each year)
- Organic Chemistry Weightage: ~30–40% (~15–20 marks)
2. Chapter-wise Weightage (Last 3 Years)
The most frequently tested chapters in Organic Chemistry Basics (CUET UG) are:
| Chapter | Weightage (Marks) | Trend |
|---|---|---|
| IUPAC Nomenclature | 3–5 marks | High |
| Isomerism (Structural Stereo) | 3–4 marks | Moderate |
| General Organic Chemistry (GOC) | 4–6 marks | High |
| Reaction Mechanisms (SN1, SN2, E1, E2) | 2–3 marks | Moderate |
| Named Reactions (Grignard, Wurtz, etc.) | 2–4 marks | Moderate |
| Aromaticity Huckel’s Rule | 2–3 marks | Low |
| Functional Group Chemistry (Alcohols, Aldehydes, etc.) | 3–5 marks | High |
| Biomolecules (Basics of Carbohydrates, Proteins, etc.) | 1–2 marks | Low |
3. Marking Pattern (2022–2024)
-
Question Type: MCQs (5 options)
-
Marking Scheme:
-
Correct Answer: +5
-
Incorrect Answer: -1
-
Unattempted: 0
-
Difficulty Level:
-
Easy (40%): Direct questions (IUPAC, functional groups)
-
Moderate (50%): Reaction mechanisms, isomerism
-
Hard (10%): Conceptual GOC (resonance, hyperconjugation)
4. Key Observations
- Most Repeated Topics:
- IUPAC naming (~1 question every year)
- GOC (Acidity/Basicity, stability of intermediates)
- SN1/SN2 reactions
- Low-Weightage Topics:
- Biomolecules (rarely asked beyond 1 mark)
- Aromaticity (only if combined with benzene reactions)
5. Preparation Tips
- Focus on High-Weightage Chapters: IUPAC, GOC, and functional groups.
- Practice Reaction Mechanisms: SN1/SN2/E1/E2 are frequently tested.
- Avoid Overemphasis on Biomolecules: Only basic definitions are asked.
- Solve Previous Papers: CUET repeats conceptual questions (e.g., hyperconjugation, inductive effect).
Conclusion
Organic Chemistry in CUET is concept-heavy but predictable , with ~15–20 marks from basics. Prioritize IUPAC, GOC, and reaction mechanisms for maximum scoring potential.
