CBSE Class 12 Chemistry Sample Papers 2026-27
Prepare for your Class 12 CBSE Board Chemistry exam (Subject Code: 043) with 20 full-length sample papers, each structured on the standard question paper pattern — 33 questions, 70 marks, 3-hour format. All questions are original and cover the complete Class 12 Chemistry syllabus.
What's Inside
Each paper follows the standard five-section structure: Section A (16 MCQs and Assertion-Reason, 1 mark each), Section B (5 Very Short Answer, 2 marks each), Section C (7 Short Answer, 3 marks each), Section D (2 Case Study questions, 4 marks each), and Section E (3 Long Answer, 5 marks each). Internal choices are provided throughout. Every paper is followed by a complete step-wise answer key with full working shown.
Topics Covered
Questions span the complete Class 12 Chemistry syllabus — Solutions (colligative properties, van't Hoff factor, molality, azeotropes), Electrochemistry (Nernst equation, Kohlrausch's Law, fuel cells, Daniel cell), Chemical Kinetics (rate laws, integrated rate equations, zero/first/second order), d and f Block Elements (lanthanoid contraction, d-block trends, Crystal Field Theory), Coordination Chemistry (IUPAC naming, VBT, spectrochemical series), Haloalkanes and Haloarenes (SN1/SN2/E2 mechanisms), Alcohols, Phenols and Ethers (Lucas test), Aldehydes and Ketones (aldol condensation, named reactions), Amines (carbylamine, diazotisation, Sandmeyer), Biomolecules (carbohydrates, amino acids, DNA base pairing, vitamins), and Polymers (PDI, addition and condensation).
Difficulty Levels
Papers are spread across three levels: Easy (Papers 1–2), Medium (Papers 3–4, 9–10, 13), and Hard (Papers 5–8, 11–12, 14–20), with each paper's key topic focus listed in the contents — allowing targeted practice on weaker areas.

Reviews
Electrochemistry section is outstanding — Nernst equation, Kohlrausch Law, fuel cells and Daniel cell all covered with application-level questions. Step-wise answer keys make every solution easy to follow.
Rate versus concentration graphs and order determination questions with graphical data are included. These are high-difficulty board questions and this material gives good practice for them.
Coordination Chemistry questions on IUPAC naming, VBT and spectrochemical series are very well framed. These are among the trickiest topics in Class 12 and the coverage here is thorough.
Section E five-mark answers show how to structure responses for full marks. Presentation and point sequencing matter in board exams and these model answers demonstrate that clearly.
Carbylamine test, diazotisation, Sandmeyer reaction and coupling reaction questions are varied and well framed. Good reinforcement of a chapter with many reactions to remember.
The question quality is genuinely high and the step-wise solutions are very helpful. The overall visual design and navigation feel a bit plain. Content is strong enough to recommend without hesitation.
Haloalkanes mechanisms, aldol condensation, carbylamine reaction, Sandmeyer reaction, diazotisation — all named reactions are covered across multiple papers. Excellent for exam preparation.
All major named reactions across organic chemistry including Lucas test, aldol condensation and Sandmeyer are present with appropriate application questions. Exactly what students need.
Trends across the d-block, Crystal Field Theory and lanthanoid contraction questions are well structured. These are complex topics and the coverage here is clear and thorough.
Section D case study questions require synthesis of multiple concepts. These are exactly the type that trip students in board exams and this material prepares you well for them.
