Preparing for the Maharashtra State Board HSC examination requires more than just reading textbooks; it demands a strategic approach to the HSC Chemistry Question Bank. As we approach the 2026 board exams, the weightage for "Applied Chemistry" chapters—Biomolecules, Polymers, and Chemistry in Everyday Life—remains a critical scoring zone for students, especially those eyeing medical careers.
These three chapters contribute approximately 9 to 12 marks (with options) to your total score. Because the concepts here are descriptive and logic-based, they provide a "safety net" for students who may find the complex numericals of Physical Chemistry challenging.
HSC Chemistry Question Bank: Official Access and Importance
The Maharashtra State Board of Secondary and Higher Secondary Education (MSBSHSE) and the State Council of Educational Research and Training (SCERT) provide official resources to streamline student preparation. Using the official HSC Chemistry Question Bank is essential because it aligns perfectly with the latest 70:30 exam pattern (70 marks theory, 30 marks practical).
To access the official repositories, students should visit:
MSBSHSE Official Question Paper Section: mahahsscboard.in

Why Focus on Applied Chemistry for 2026?
In the 2026 exam cycle, there is an increased emphasis on application-oriented questions. For aspiring medical students, Biomolecules and Chemistry in Everyday Life are foundational for first-year MBBS subjects like Biochemistry and Pharmacology. Mastering these now gives you a significant head start.
Chapter 14: Biomolecules – Essential Questions
Biomolecules focus on the "Chemistry of Life." In the HSC Chemistry Question Bank, this chapter is high-yield for both Very Short Answer (VSA) and Long Answer (LA) questions.
Most Repeated Questions
Carbohydrates: Define Carbohydrates. Classify them into Monosaccharides, Oligosaccharides, and Polysaccharides with examples.
Glucose Structure: Draw the Haworth projection formula of \alpha-D-glucopyranose and \beta-D-glucopyranose.
Proteins: What are Essential and Non-essential Amino Acids? Explain the denaturation of proteins.
Nucleic Acids: Distinguish between DNA and RNA. Define Nucleoside and Nucleotide.
High-Value Concepts for Medical Aspirants
Peptide Linkage: Understand the formation of the CO-NH bond.
Vitamins: Memorize the table of vitamins, their sources, and deficiency diseases (e.g., Vitamin C - Scurvy, Vitamin K - Delayed blood clotting).
Chapter 15: Introduction to Polymer Chemistry
Polymers are the backbone of modern materials. The 2026 HSC Chemistry Question Bank emphasizes the environmental impact and medical uses of polymers.
Important Questions for 2026
Classification: Explain the classification of polymers based on source (Natural, Synthetic, Semi-synthetic).
Polymerization Mechanisms: Distinguish between Addition (Chain-growth) and Condensation (Step-growth) polymerization.
Specific Polymers: Write the monomers and one use for:
Nylon-6,6 (Hexamethylenediamine + Adipic Acid)
Terylene/Dacron (Ethylene Glycol + Terephthalic Acid)
Bakelite (Phenol + Formaldehyde)
Teflon (Tetrafluoroethene)
Focus on Biodegradable Polymers
Given the 2026 sustainability trends, questions on PHBV and Nylon-2-Nylon-6 are highly probable. These are crucial for medical sutures and orthopedic implants.
Chapter 16: Chemistry in Everyday Life – Medical Perspectives
This chapter is a goldmine for easy marks. It directly connects chemical structures to their biological effects.
Key Questions to Master
Analgesics & Antipyretics: Define and give examples (e.g., Aspirin, Paracetamol). Explain the anti-blood-clotting action of Aspirin.
Antiseptics vs. Disinfectants: Differentiate between them with examples. Why is 0.2% phenol an antiseptic while 1% is a disinfectant?
Antibiotics: Explain the difference between Broad-spectrum and Narrow-spectrum antibiotics with examples like Penicillin and Chloramphenicol.
Cleansing Agents: Explain the mechanism of the cleansing action of soap. What is the difference between Soaps and Synthetic Detergents?
Analyzing Exam Trends for 2026
Based on the analysis of the last five years of Maharashtra Board papers, the following trends are emerging:
MCQs: At least 2-3 MCQs will come from these three chapters, often focusing on monomer names or vitamin deficiency.
Distinction Tables: Comparing DNA vs. RNA or Thermoplastic vs. Thermosetting polymers is a staple for 2-mark questions.
Structure Drawing: You must practice drawing the basic structures of Glucose and Sucrose.
Important Formulas and Relations
While this section of the syllabus is less math-heavy than others, ensure you know:
Degree of Polymerization (relationship between molecular weight of polymer and monomer).
Formula Name: Polydispersity Index (PDI) - used to measure the distribution of molecular mass in a polymer sample.
Conclusion
Success in the 2026 Maharashtra Board exams lies in balancing heavy numerical chapters with these descriptive "Applied Chemistry" topics. By utilizing the HSC Chemistry Question Bank, focusing on repeated questions, and understanding the medical relevance of biomolecules and drugs, you can easily secure 10-12 marks with minimal effort.
