Preparing for the Maharashtra State Board Class 12 examinations requires more than just hard work; it requires a strategic approach to the vast syllabus. The HSC Chemistry Question Bank 2026 serves as a vital compass for students navigating the intricate world of Organic Chemistry. Specifically, the chapters covering Alcohols, Phenols, Ethers, Aldehydes, Ketones, Carboxylic Acids, and Amines form the backbone of the paper, carrying significant weightage and high relevance for medical entrance exams like NEET and FMGE.
In 2026, the Maharashtra State Board (MSBSHSE) has maintained a rigorous 70-mark theory and 30-mark practical structure. This guide provides an in-depth analysis of the most repeated questions, chapter-wise weightage, and official links to help you secure a top-tier score.
Maharashtra HSC Chemistry Paper Pattern 2026
Understanding the structure of your exam is the first step toward mastery. The 2026 theory paper is divided into four distinct sections:
Section | Type of Questions | Marks Allocation |
Section A | 10 MCQs + 8 Very Short Answers (VSA) | 18 Marks (Compulsory) |
Section B | 8 out of 12 Short Answers (SA-I) | 16 Marks (2 marks each) |
Section C | 8 out of 12 Short Answers (SA-II) | 24 Marks (3 marks each) |
Section D | 3 out of 5 Long Answers (LA) | 12 Marks (4 marks each) |
For aspiring medical students, Section C and D are crucial. They often feature multi-step organic synthesis and mechanisms that test your conceptual depth, similar to the logic required in professional medical licensing exams.
Chapter-Wise Weightage for Organic Chemistry 2026
The HSC Chemistry Question Bank 2026 highlights that Organic Chemistry contributes approximately 18–25 marks to the total paper. Prioritizing these chapters is essential for scoring 90+.
Aldehydes, Ketones, and Carboxylic Acids: 8 Marks (with options) – The "King" of Organic Chemistry.
Alcohols, Phenols, and Ethers: 6 Marks (with options).
Amines: 4 Marks (with options).
Halogen Derivatives: 7 Marks (with options).
Important Questions from the HSC Chemistry Question Bank 2026
1. Alcohols, Phenols, and Ethers
This chapter is a favorite for testing chemical properties and acidity trends.
Most Repeated Questions:
Explain why Phenols are more acidic than Alcohols.
Write a note on the Williamson Synthesis for preparing ethers.
Explain the preparation of Phenol from Cumene (Commercial method).
What is the action of Lucas Reagent on primary, secondary, and tertiary alcohols?
Distinction Test: How will you distinguish between Ethanol and Phenol using neutral Ferric Chloride?
2. Aldehydes, Ketones, and Carboxylic Acids
This chapter is heavy on "Named Reactions," which are almost guaranteed to appear in Section C or D.
Essential Named Reactions:
Aldol Condensation: Mechanism and reaction for Ethanal.
Cannizzaro Reaction: Why do Formaldehyde and Benzaldehyde undergo this reaction?
Rosenmund Reduction: Preparation of aldehydes from acyl chlorides.
Clemmensen & Wolff-Kishner Reduction: Converting carbonyl groups to alkanes.
Reasoning Based:
Why are Carboxylic Acids stronger acids than Phenols?
Explain the acidity of Alpha-hydrogen in aldehydes.
3. Amines
Though it carries fewer marks, this chapter provides easy, "scoring" questions that shouldn't be ignored.
Key Concepts:
Hoffmann Bromamide Degradation: A vital step-down reaction.
Gabriel Phthalimide Synthesis: Why is it preferred for primary aliphatic amines?
Hinsberg’s Test: Distinguishing between 1°, 2°, and 3° amines.
Carbylamine Reaction: Test for primary amines (Foul-smelling isocyanide).
Essential Formula and Concepts to Remember
While we avoid complex mathematical derivations here, mastering the following formula-based concepts is necessary for solving the "Chemical Kinetics" or "Solutions" sub-parts often mixed with Organic questions:
Raoult’s Law (Vapor pressure calculations)
Nernst Equation (Electrochemical cells)
Hess’s Law of Constant Heat Summation
Rate Law Expressions (For reaction mechanisms)
Henry’s Law Constant
Medical Perspective: Why Organic Chemistry Matters
For students looking toward the FMGE 2026 or NEET, Organic Chemistry is the foundation of Pharmacology and Biochemistry. Understanding how a Carboxylic Acid group interacts with a cell receptor or how Amines function in neurotransmitters (like Dopamine and Epinephrine) starts with these Class 12 fundamentals. The HSC Chemistry Question Bank 2026 isn't just an exam tool; it’s the first step in your medical career.

Conclusion
Success in the HSC 2026 exam lies in balancing the "Big Three" chapters of Organic Chemistry with regular practice of the official question banks. By focusing on named reactions, acidity trends, and the official paper pattern, you can turn Chemistry from a challenging subject into your highest-scoring one.
Frequently Asked Questions (FAQs)
How can I download the official HSC Chemistry Question Bank 2026?
You can download the official HSC Chemistry Question Bank 2026 from the SCERT Maharashtra website (maa.ac.in). It is usually listed under the "Prashnapedhi" section for Class 12.
Which is the most important chapter in the HSC Chemistry 2026 syllabus?
Based on the 2026 weightage, Aldehydes, Ketones, and Carboxylic Acids is the most important chapter in Organic Chemistry, carrying 8 marks with options.
Are the questions from the SCERT Question Bank repeated in the board exam?
Yes, historically, about 60–70% of the concepts and types of questions in the board exam are reflected in the official question bank. It is an excellent tool for identifying high-probability topics.
Can I skip Amines if I am short on time?
It is not recommended. While it has a lower weightage (4 marks), the questions (like the Carbylamine test or Hoffmann Bromamide) are very direct and take very little time to master.
