Karnataka 2nd PUC Chemistry Syllabus 2025–26 | Complete Guide
2nd PUC Chemistry plays a critical role in KCET, NEET, and board exam results. The Karnataka 2nd PUC Chemistry syllabus 2025–26 covers Physical, Inorganic, and Organic Chemistry with a 70-mark theory paper and 30-mark practical exam.
At Giraffe Learning, Chemistry is approached as a scoring subject balancing numericals, reactions, and trends so students prepare once and perform confidently in both board exams and competitive entrances.
Why 2nd PUC Chemistry Matters for Boards, KCET & NEET
Karnataka 2nd PUC Chemistry forms the backbone of engineering and medical entrance preparation. Nearly 90% of KCET and NEET Chemistry overlaps directly with the PUC II syllabus, making focused board preparation extremely effective.
The syllabus includes 16 units, ranging from Solid State to Everyday Chemistry, and follows a rationalised structure with deleted portions clearly marked by DPUE. Organic Chemistry carries the highest weightage, while Physical Chemistry numericals and Inorganic trends add consistent scoring opportunities.
With the right strategy, students can confidently aim for 60+ out of 70 in theory, with practical marks significantly boosting the final score.

Chapter-Wise Weightage: What to Study First
| Unit Group | Marks Range | Key Focus |
|---|---|---|
| Organic Chemistry (Units 10–16) | 25–30 | Named reactions, conversions |
| Physical Chemistry (Units 1–5) | 20–25 | Numericals, formulas |
| Inorganic Chemistry (Units 6–9) | 15–20 | Trends, compounds |
Insight: Organic Chemistry consistently carries the highest weightage. Giraffe Learning prioritises reactions and mechanisms early in the year.
Practical & Lab Components: How to Score Full Marks
Chemistry practicals contribute 30 valuable marks.
- Volumetric analysis (15 marks): Acid–base and redox titrations
- Salt analysis (8 marks): Systematic detection of anions and cations
- Content-based experiment (5 marks): Rate of reaction, viscosity, or surface tension
- Viva + record (2 marks): Based on experiments and theory
Students should practise the complete salt analysis scheme and focus on clean observations, confirmatory tests, and proper record maintenance.
Chemistry Practical Examination – Marks Distribution
| Component | Details | Marks |
|---|---|---|
| Volumetric Analysis | Acid–base titrations, redox titrations | 15 |
| Salt Analysis | Systematic detection of anions and cations | 8 |
| Content-based Experiment | Experiments on rate of reaction, viscosity, or surface tension | 5 |
| Viva Voce + Record Work | Oral examination and practical record evaluation | 2 |
| Total | 30 | |
