JEE Main 2025 and NEET 2025 each carried a HOTS item on The d- and f-Block Elements whose stem mirrored an Exemplar problem from this chapter almost verbatim. The NCERT Exemplar (renumbered from legacy Ch 8 to current Ch 4) is the single resource entrance-paper setters use to draft inorganic HOTS questions.
- CBSE Weightage: 4 to 6 marks (Class 12 Chemistry Boards)
- JEE Main Weightage: 2 to 3% (around 1 to 2 questions per shift drawn from this chapter)
- NEET Weightage: 2 to 3 question(s) per year
The article below covers The d- and f-Block Elements Class 12 Chemistry Exemplar Book PDF, the question-type split, and a parallel-track study plan.
Curated by Collegedunia subject experts, mapped to the 2026-27 NCERT print, and cross-referenced with the last two sittings of CBSE Boards, JEE Main, and NEET.

The d- and f-Block Elements NCERT Exemplar Question-Type Breakdown
The 2026-27 Exemplar print splits this chapter across six question types. The table tells you how many of each kind you face and the indicative mark value used in the Exemplar's own scheme.
| Question Type | Number of Problems | Indicative Marks Each |
|---|---|---|
| MCQ-I (single correct) | 18 | 1 |
| MCQ-II (one or more correct) | 10 | 2 |
| Short Answer (SA) | 17 | 2 to 3 |
| Matching Type | 4 | 3 |
| Assertion and Reason | 5 | 1 |
| Long Answer (LA) | 4 | 5 |
| Total | 58 | - |
MCQ-II is the most-failed type in The d- and f-Block Elements because at least one option besides the obvious one is correct, usually a second oxidation state or a second cause of colour. Treat it as a slow type, not a quick one.

How will Collegedunia's NCERT Exemplar Book PDF Help You with The d- and f-Block Elements?
This page hosts the official 2026-27 print and adds the practice-strategy layer a raw Exemplar PDF lacks.
- 2026-27 NCERT Alignment: Every problem in the 58-question set is mapped to a sub-topic that still belongs to the current Class 12 Chemistry syllabus.
- Question-Type Inventory: A clear count of MCQ-I, MCQ-II, SA, Matching, Assertion-Reason, and LA problems lets you pace each sitting against the load.
- Self-Test Format: The book prints only the problems, so you attempt cold, flag weak ones, and revisit them in the final revision week.
- JEE and NEET Crossover: Recent JEE Main and NEET sittings reuse Exemplar d-block setups almost verbatim, lifting your entrance score for the chapter.
The d- and f-Block Elements Top Reactions and Formulae to Memorise Before Attempting the Exemplar
Most Exemplar d-block problems hinge on a small set of recurring half-reactions and one magnetic-moment formula. Lock these into memory before opening the PDF; you will save 30 to 40% of attempt time.
| Concept | Expression |
|---|---|
| Spin-only magnetic moment | s = √n(n+2) BM (n = unpaired electrons) |
| Acidic permanganate half-reaction | MnO4- + 8H+ + 5e- → Mn2+ + 4H2O |
| Acidic dichromate half-reaction | Cr2O72- + 14H+ + 6e- → 2Cr3+ + 7H2O |
| Chromate-dichromate equilibrium | 2CrO42- + 2H+ Cr2O72- + H2O |
| Lanthanoid configuration (general) | [Xe] 4f1-14 5d0-1 6s2 |

The d- and f-Block Elements Exemplar vs NCERT Textbook: Difficulty Comparison
The Exemplar twists setups you have already met in the textbook. The shift is usually one of three kinds, shown below.
| Setup | NCERT Textbook | Exemplar Twist |
|---|---|---|
| Spin-only magnetic moment | Given n, find μ | Given μ = 5.92 BM, identify the d-block ion (Mn2+ or Fe3+) and justify |
| Oxidation state | State the most stable oxidation state of Mn | Explain why Cu+ is less stable than Cu2+ in aqueous solution despite a stable d10 configuration |
| Lanthanoid contraction | State the contraction | Identify which 4d-5d pair has near-identical radii AND justify with the contraction |
| KMnO4 oxidation | Write the balanced half-reaction | Identify the product when KMnO4 is reduced in neutral, alkaline, and acidic media in the same prompt |
2026-27 Syllabus Status of The d- and f-Block Elements Exemplar Problems
The NCERT Exemplar publication was not refreshed when the textbook was trimmed. Most Chapter 8 (legacy) Exemplar problems still map to the current Class 12 Chemistry Chapter 4, but a small minority touch dropped sub-topics. Skip those during board prep, but keep them if you are working the book for JEE Main or NEET, where the full scope still matters.
Detailed kept-trimmed-removed table: see the breakdown on the The d- and f-Block Elements Class 12 Chemistry NCERT Book PDF page.
Why the NCERT Exemplar Matters for JEE Main and NEET d-Block Prep
The NCERT Exemplar is the official NCERT publication that paper-setters reference when they design HOTS problems for the CBSE Board and the JEE Main / NEET papers. Three reasons it earns a slot in your plan:
- Same author body: The committees that write the NCERT textbook and Exemplar overlap, so the Exemplar trains you on the exact phrasing CBSE markers expect.
- Six question types: Few other resources cover MCQ-I, MCQ-II, SA, Matching, Assertion-Reason, and LA in one book; the mix matches today's CBSE paper and the JEE Main multiple-correct trap-style.
- Free and offline: The PDF works on a phone with no reader app. Print only the section you need without buying a private question bank.
Boards toppers consistently cite the Exemplar as the single book that lifted their d-block attempts from a B1 to an A1.

Time-per-Question Budget for The d- and f-Block Elements Exemplar
A realistic time map helps you plan how many sittings the chapter PDF needs. Numbers below are the average attempt time for a student who has already finished the NCERT chapter.
| Question Type | Problems | Avg. Minutes Each | Total Time |
|---|---|---|---|
| MCQ-I and MCQ-II | 28 | 3 to 5 | ~ 115 min |
| SA, Matching, Assertion-Reason | 26 | 5 to 8 | ~ 170 min |
| LA | 4 | 20 to 25 | ~ 90 min |
| Whole chapter | 58 | - | ~ 6 hours |
Spread the six-hour load across four to five sittings, back-to-back LA attempts cause fatigue and skipped half-reaction balancing.

Ans. The NCERT Exemplar publication has not been refreshed since the textbook was rationalised, so its internal numbering still reads Chapter 8. In the current 2026-27 Class 12 Chemistry syllabus the chapter sits at position 4, because three earlier inorganic units were removed from the textbook. The chapter content itself is unchanged.
Ques. Is the Exemplar Book PDF aligned with the 2026-27 NCERT?
Ans. The NCERT Exemplar publication was not refreshed when the textbook was trimmed. The bulk of the d-block Exemplar problems still map to the current 2026-27 textbook chapter; a small minority touch alloy and named-catalyst sub-topics that were trimmed and can be skipped during board preparation.
Ques. How many pages is the Class 12th Chemistry Chapter 4 Exemplar Book PDF?
Ans. The d- and f-Block Elements Exemplar PDF runs approximately 14 pages and packs 58 HOTS problems across MCQ-I, MCQ-II, SA, Matching, Assertion-Reason, and LA types.
Ques. How many problems does this chapter of the Exemplar contain?
Ans. The d- and f-Block Elements Exemplar chapter holds 58 problems in total, split as MCQ-I (18), MCQ-II (10), SA (17), Matching (4), Assertion-Reason (5), and LA (4).
Ques. Are d-block Exemplar problems compulsory for the CBSE Class 12 board exam?
Ans. Exemplar problems are not part of the prescribed NCERT textbook chapter, but CBSE has used Exemplar-style HOTS items from the d-block in four of the last five board papers. For an A1 grade in Chemistry, working the Exemplar is practically required.
Ques. Where can I find the solutions to the d-block Exemplar problems?
Ans. Worked answers for every problem in this chapter are on the The d- and f-Block Elements Class 12 Chemistry NCERT Exemplar Solutions page.
Ques. How long does it take to finish this chapter of the Exemplar Book?
Ans. Plan for around 6 hours spread across four to five sittings: roughly two hours for the MCQ-I and MCQ-II types, around three hours for the SA, Matching, and Assertion-Reason set, and the rest for the LA section. Revisit any wrong attempts the same day to lock in the correction.
Ques. Can I use the Exemplar Book for JEE Main and NEET d-block preparation?
Ans. Yes. JEE Main 2024 and 2025 each carried at least one d-block question whose setup mirrored an Exemplar problem from this chapter. NEET also reuses Exemplar MCQ-II patterns on lanthanoid contraction and magnetic moment. Use the PDF during your year, then revisit before the entrance.
