EXEMPLAR BOOK PDF · CLASS 12 CHEMISTRY
Class 12 Chemistry - Exam Weightage
Class 12 Chemistry is worth about 200 marks combined across CBSE Boards, JEE Main, JEE Advanced and NEET UG. That makes it the second-heaviest science subject after Physics on these big exams.
Class 12 Chemistry Exemplar Weightage Snapshot (CBSE 2026 Theory Paper)
The Exemplar problems follow the same chapter weightage as the main NCERT. Inorganic Chemistry (Coordination + d/f Block) gives you 14 marks of the 70-mark theory paper. This is also where most of the hardest Exemplar problems sit.
| Chapter | Topic | CBSE Marks (2026) | JEE Main 2025 Qs |
|---|---|---|---|
| Ch 4 | The d- and f-Block Elements | 7 marks | 2 |
| Ch 5 | Coordination Compounds | 7 marks | 2 |
| Ch 1 | Solutions | 7 marks | 1 |
| Ch 8 | Aldehydes, Ketones and Carboxylic Acids | 7 marks | 2 |
| Ch 2 | Electrochemistry | 6 marks | 1 |
| Ch 3 | Chemical Kinetics | 6 marks | 1 |
| Ch 7 | Alcohols, Phenols and Ethers | 6 marks | 1 |
| Ch 10 | Biomolecules | 6 marks | 1 |
| Ch 6 | Haloalkanes and Haloarenes | 5 marks | 1 |
| Ch 9 | Amines | 5 marks | 1 |
Class 12 Chemistry CBSE 2026 Paper Pattern Snapshot
The 70-mark CBSE Class 12 Chemistry theory paper runs 3 hours and has five sections. Knowing the weight of each section is half the revision plan. Once you know which section a chapter feeds, you can pick the right resource. Use Notes for Section A recall and NCERT Solutions for Sections C and D working.
- Section A (16 questions of 1 mark each): MCQs and assertion-reason; tests definitions, named-reaction recall, and reaction-product prediction.
- Section B (5 questions of 2 marks each): Very short answer; one-step questions on named reactions, conversion sequences, and reasoning.
- Section C (7 questions of 3 marks each): Short answer; numerical problems on colligative properties, Nernst equation, kinetics, plus reaction-mechanism questions.
- Section D (2 case-study questions of 4 marks each): Application of coordination chemistry, electrochemistry, or biomolecules to a passage.
- Section E (3 questions of 5 marks each): Long answer; usually one inorganic (d / f-block or coordination), one organic synthesis, and one physical-chemistry problem.
The 70-mark theory paper plus the 30-mark internal assessment (practical, project, viva) makes the 100-mark scheme. Your internal marks rise as you complete the lab notebook and prepare for the viva. The theory paper is where your chapter-wise NCERT work shows.
Where to Start with the Class 12 Chemistry Exemplar
Start with the six high-weightage chapters where Exemplar practice gives you the biggest marks gain:
- Chapter 4, The d- and f-Block Elements (7 marks): the inorganic core of the paper. Lanthanide contraction, magnetic behaviour, and oxidation-state comparison are common LA questions.
- Chapter 5, Coordination Compounds (7 marks): VBT, CFT, and isomerism in coordination complexes come up often on the board paper and score well on NEET.
- Chapter 1, Solutions (7 marks): colligative properties numericals carry sure marks. Van't Hoff factor problems test both formula recall and use.
- Chapter 8, Aldehydes, Ketones and Carboxylic Acids (7 marks): named reactions (Cannizzaro, aldol, Clemmensen, Wolff-Kishner) give you 4-5 marks each. This is the reaction-mechanism block in organic chemistry.
- Chapter 2, Electrochemistry (6 marks): Nernst equation problems and conductance sums are common 3-mark questions.
- Chapter 3, Chemical Kinetics (6 marks): first-order rate-constant problems and half-life sums become easy once you practise them.

How to Use the Class 12 Chemistry Exemplar Most Effectively
5-STEP METHOD · CBSE TOPPER ROUTINE
How to Use the Exemplar Book PDF - Class 12 Chemistry
- 1Read the chapter first. Open the NCERT Book PDF or chapter Notes. This resource assumes you already know the concepts.
- 2Attempt each question on your own. Write the working in a notebook before you open the answer. Just reading answers does not build exam speed.
- 3Compare your working to the resource. Mark every step where your method differed. Those spots lose marks on the board paper.
- 4Flag questions that take over 7 minutes. Put these on your re-attempt list for the final-week revision pass.
- 5Pair Exemplar problems with the Exemplar Solutions PDF. Try first, then look only when you are stuck for 10 or more minutes. The Solutions PDF on the sibling listing has the checked working.
- After you finish each chapter's back-exercise: do the Exemplar's MCQ section first (10-15 minutes per chapter), then move to MCQ-II and SA.
- 2 months before JEE / NEET: do the SA and LA sections of every high-weightage chapter. Mark every problem you cannot solve in under 10 minutes for re-attempt.
- Last 4 weeks before the boards: go back to the marked problems and check your answers against the Exemplar Solutions.
- Skip the Exemplar in the final week: Exemplar problems are too long for night-before revision. Switch to the Notes and Formula Sheet then.
Common Mistakes Class 12 Chemistry Students Make with the Exemplar
- Writing oxidation states without checking electron count: Chapter 4 students often write Mn(IV) without recalling the d3 configuration. Always check the d-electron count against the oxidation state before you answer.
- Skipping the geometry reason on Coordination questions: Chapter 5 questions reward the geometry-and-magnetism reason. State the hybridisation, the geometry, and the magnetic behaviour (paramagnetic or diamagnetic) in every coordination compound answer.
- Mixing up SN1 and SN2 conditions: Chapter 6 students apply SN2 to tertiary substrates. SN2 is single-step bimolecular and prefers primary substrates. SN1 is two-step unimolecular and prefers tertiary.
- Forgetting Markovnikov's rule on alcohol formation: Chapter 7 students often write the wrong product of acid-catalysed hydration. The OH adds to the more substituted carbon and the H adds to the less substituted one.
- Writing 'aldol' for any base-catalysed reaction: Chapter 8 students label every base-catalysed reaction as an aldol condensation. The aldol step needs alpha-hydrogen. Without alpha-hydrogen, the Cannizzaro reaction happens instead.
- Confusing colligative property formulas: Chapter 1 numericals need the correct formula for each property. Relative lowering uses mole fraction, elevation and depression use molality times Kb or Kf, and osmotic pressure uses cRT.
- Drawing structural formulas without lone pairs: Chapter 9 amines and Chapter 5 coordination questions both reward the lone-pair-on-nitrogen sketch. If you skip the lone pair on the basicity-comparison answer, you lose marks.
Student Feedback: What 14,380 Class 12 Chemistry Students Told Us
What 14,380 students told us about their Class 12 Chemistry Exemplar usage
- 72% of students rated Chapter 5 Coordination Compounds as the highest-effort chapter, ahead of Chapter 4 The d- and f-Block Elements at 61% and Chapter 3 Chemical Kinetics at 49%.
- Most-skipped chapter: Chapter 9 Amines (about 26% of students skip it, even though it carries 5 marks). Toppers said this chapter is worth winning back, because the diazonium salt reactions come up every year.
- Toppers said that working the Expert's Solution tab on every Chapter 4 The d- and f-Block Elements problem added 4-6 marks to their 70-mark theory score. Most of it came from the lanthanide-contraction and oxidation-state comparison questions.
- The average Class 12 Chemistry student spent 52 hours across the 10 chapters to finish the NCERT back-exercise once. Chapters 4, 5, 7, and 8 took the most time per question.
