- 4 min read
reparing for the Maharashtra HSC Chemistry exam in 2026 requires more than just reading the textbook from cover to cover. To score a distinction, you need a roadmap that tells you exactly where to invest your time. By understanding the HSC Chemistry chapter wise weightage 2026, you can differentiate between "must-know" high-scoring topics and smaller, supplementary chapters.
In the 2026 session, the Maharashtra State Board (MSBSHSE) continues to follow the 70:30 pattern—70 marks for the theory paper and 30 marks for internal practicals. However, the distribution within that theory paper is what determines your final percentage.
Detailed HSC Chemistry Chapter Wise Weightage 2026
The Chemistry syllabus is broadly categorized into four sections: Physical, Inorganic, Organic, and Applied Chemistry. Below is the verified weightage for each chapter, including marks with and without options.
Physical Chemistry (26 Marks)
This section is the backbone of your paper, especially for numerical-based questions in Section B and C.
Chapter Name | Marks (Without Option) | Marks (With Option) |
Solid State | 3 | 5 |
Solutions | 4 | 6 |
Ionic Equilibria | 4 | 6 |
Chemical Thermodynamics | 6 | 8 |
Electrochemistry | 5 | 7 |
Chemical Kinetics | 4 | 6 |
Inorganic Chemistry (17 Marks)
Inorganic chemistry often features descriptive and structured questions.
Chapter Name | Marks (Without Option) | Marks (With Option) |
Elements of Groups 16, 17, & 18 | 6 | 8 |
Transition & Inner Transition Elements | 6 | 8 |
Coordination Compounds | 5 | 7 |
Organic Chemistry (18 Marks)
Organic Chemistry is often considered the most challenging but is highly rewarding if you master the reaction mechanisms.
Chapter Name | Marks (Without Option) | Marks (With Option) |
Halogen Derivatives | 5 | 7 |
Alcohols, Phenols, and Ethers | 4 | 6 |
Aldehydes, Ketones, and Carboxylic Acids | 6 | 8 |
Amines | 3 | 4 |
Applied Chemistry (9 Marks)
These are often considered "scoring" chapters as they are relatively easy to memorize.
Chapter Name | Marks (Without Option) | Marks (With Option) |
Biomolecules | 3 | 4 |
Introduction to Polymer Chemistry | 3 | 4 |
Green Chemistry and Nanochemistry | 3 | 4 |

High-Priority Units for HSC Chemistry 2026
To achieve the highest impressions on your scorecard, focus on these "Big Three" areas that carry the maximum HSC Chemistry chapter wise weightage 2026:
Chemical Thermodynamics (8 Marks with options): This chapter is a regular feature in Section D (Long Answers). Ensure you practice the derivations for work done in isothermal reversible processes and Hess’s Law.
p-Block Elements (Elements of Groups 16, 17, 18): Carrying 8 marks, this is the heaviest chapter in Inorganic Chemistry. Focus on structures of oxoacids and the anomalous behavior of elements.
Aldehydes, Ketones, and Carboxylic Acids: This is the king of Organic Chemistry. Named reactions like Aldol Condensation and Cannizzaro reaction are almost certain to appear.
Smart Study Strategy based on 2026 Weightage
Section-Wise Mastery: Start with Physical Chemistry numericals. They are predictable and follow a fixed set of formulas from chapters like Solutions and Chemical Kinetics.
Reaction Notebook: For Organic Chemistry, maintain a dedicated notebook for all named reactions. The 2026 paper pattern suggests that roughly 20% of the paper will test direct reaction conversions.
The 25% Objective Rule: Since 25% of the paper consists of objective-type questions (MCQs and VSA), do not ignore the small "Applied Chemistry" chapters. They provide easy marks that can boost your aggregate without requiring complex derivations.

HSC Chemistry Exam Pattern 2026
The paper is divided into four main sections to test different cognitive levels:
Section A: 10 MCQs and 8 Very Short Answers (18 Marks) - Tests basic concepts and definitions.
Section B: 8 out of 12 Short Answers (16 Marks) - Focuses on simple numericals and laws.
Section C: 8 out of 12 Short Answers (24 Marks) - Involves detailed explanations and 2-step numericals.
Section D: 3 out of 5 Long Answers (12 Marks) - High-weightage derivations and complex reactions.
FAQs on HSC Chemistry Chapter Wise Weightage 2026
Q: Which chapter has the highest HSC Chemistry chapter wise weightage 2026?
The chapters with the highest weightage (8 marks with options) are Chemical Thermodynamics, p-Block Elements, and Aldehydes, Ketones, and Carboxylic Acids.
Q: Is the 2026 Chemistry syllabus different from 2025?
No, the syllabus remains consistent. However, the 2026 marking scheme emphasizes a 70-mark theory and 30-mark practical split, with a focus on conceptual application.
Q: Can I pass HSC Chemistry by studying only high-weightage chapters?
While focusing on high-weightage chapters helps you score 40-50 marks easily, covering the entire syllabus is recommended to tackle the compulsory MCQ section.
Q: How many numericals are expected in the 2026 paper?
Historically, numericals account for 12-15 marks, primarily from the Physical Chemistry section.
Conclusion
Success in the HSC Chemistry 2026 exam is a result of tactical planning. By prioritizing chapters with the highest HSC Chemistry chapter wise weightage 2026, you ensure that even if time runs short, you have secured the most significant portion of the marks.
