According to Reddit and student opinions, the Solutions chapter in Physical Chemistry is a section that requires less effort and gives good returns in the JEE Main exam. By memorising the essential formulas and practising questions on molarity, mole concept, and molality, you can easily score 2-3 marks from this section.
- The questions asked in the Solutions chapter are mostly formula-based and direct.
- An understanding of logarithmic scales is essential for calculations, especially in problems involving osmotic pressure, molar mass, and concentration.

Most Important Solutions Topics for JEE Main 2026
- In the Solutions chapter, the expected weightage of subtopics varies between 5% to 30% each year.
- Most questions are asked from the concentration terms, including mole fraction, molarity, and molality, as well as colligative properties.
- Therefore, according to the JEE Main 2026 syllabus, these two topics are crucial in the Solutions chapter.
| Topic | Expected Weightage (%) |
|---|---|
| Concentration Terms (Mole fraction, Molarity, Molality) | 25–30% |
| Raoult’s Law (Ideal Solutions) | 15–20% |
| Vapour Pressure & Buffer Solutions | 10–15% |
| Colligative Properties (ΔTb, ΔTf) | 20–25% |
| Abnormal Molar Mass & van’t Hoff Factor (i) | 15–20% |
| Osmotic Pressure | 5–10% |
