b) Chemistry Board Paper Pattern 2025-26 - Section-wise

The Chemistry paper follows a comprehensive pattern covering theoretical concepts, numerical problems, and practical applications across all three branches of chemistry.

Section A: Multiple Choice Questions (20 marks)

• 20 MCQs covering all units with 1 mark each
• Topics include chemical kinetics, coordination compounds, organic reactions, and electrochemistry

Section B: Very Short Answer Questions (10 marks)

• 5 questions worth 2 marks each
• Quick concept explanations, chemical equations, and basic numerical problems

Section C: Short Answer Questions (21 marks)

• 7 questions worth 3 marks each
• Mechanism explanations, calculation-based problems, and structure determinations

Section D: Long Answer Questions (15 marks)

• 3 questions worth 5 marks each
• Detailed reaction mechanisms, complex numerical problems, and comprehensive explanations

Section E: Case Study Questions (4 marks)

• 1 case-based question with sub-parts
• Real-life applications of chemical concepts

Key topics include: Chemical Kinetics, Electrochemistry, Coordination Compounds, Aldehydes & Ketones, Carboxylic Acids, Amines, Biomolecules, and Polymers.

How Does the Two-Exam Format Affect Chemistry Preparation?

The new format introduces two full exams in a year, requiring a focused and structured preparation plan:

• November Exam (Exam 1): May feature questions based on fundamental concepts, basic reaction mechanisms, and core physical chemistry calculations
• March Exam (Exam 2): Will likely include advanced organic synthesis, complex coordination chemistry, and detailed electrochemical processes

How Studying Chemistry Sample Papers 2025-26 Before Exams Helps?

• Mastering numerical problems in chemical kinetics, thermodynamics, and electrochemistry
• Understanding organic reaction mechanisms and name reactions
• Improving speed in writing chemical equations and structural formulas
• Building confidence in explaining industrial processes and their applications
• Developing analytical skills for identifying unknown compounds
• Getting familiar with IUPAC nomenclature and stereochemistry concepts

How to Use Chemistry Sample Papers 2025-26 Effectively?

• Practice in timed conditions: Especially for numerical problems and mechanism writing
• Focus on clear chemical equations: Write balanced equations with proper state symbols and conditions
• Refer to marking schemes: To understand expected level of detail in mechanism explanations
• Master all three branches equally: Ensure balanced preparation across Physical, Organic, and Inorganic Chemistry
• Practice diagram accuracy: For molecular structures, apparatus diagrams, and crystal lattices
• Use sample papers to strengthen problem-solving: Practice molarity calculations, rate law derivations, and organic synthesis pathways

In conclusion, regular practice with Class 12 Chemistry sample papers is key to mastering the dual-exam format and excelling in both board exams. These papers help you build chemical thinking, refine your problem-solving skills, and gain confidence in tackling both theoretical concepts and numerical applications.
