Coordination Compounds NCERT Exemplar Question-Type Breakdown
The 2026-27 Exemplar print splits Chapter 5 (legacy Chapter 9) 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) | 25 | 1 |
| MCQ-II (one or more correct) | 14 | 2 |
| Short Answer (SA) | 22 | 2 to 3 |
| Matching Type | 4 | 3 |
| Assertion and Reason | 5 | 1 |
| Long Answer (LA) | 5 | 5 |
| Total | 75 | - |
MCQ-II is the most-failed type in Coordination Compounds because at least one option besides the obvious one is correct, and the trap usually lives in the geometric-vs-optical isomer or strong-vs-weak-field-ligand confusion.

What's Inside the Coordination Compounds Class 12 Chemistry Exemplar PDF
The Exemplar runs about 20 pages and packs the 75 problems into six question-type sections. The topic map below tells you where each sub-topic is concentrated so you can target your weakest area without scanning the whole chapter.
| Sub-Topic Concentration | Where in the Exemplar |
|---|---|
| Werner's theory, primary/secondary valencies | Q 1, 2, 3, 47 |
| IUPAC nomenclature of mononuclear complexes | Q 4, 5, 7, 8, 9, 48, 49, 50, 70 |
| Coordination number, denticity, chelate effect | Q 10, 11, 12, 13, 14, 51, 52 |
| Isomerism (geometric, optical, structural) | Q 6, 15, 16, 17, 18, 19, 20, 53, 54, 55, 71, 72 |
| VBT, hybridisation, inner/outer orbital complexes | Q 21, 22, 23, 24, 25, 26, 27, 56, 57, 58, 73 |
| CFT, splitting, CFSE, spectrochemical series | Q 28, 29, 30, 31, 32, 33, 34, 35, 59, 60, 61, 74 |

How will Collegedunia's NCERT Exemplar Book PDF Help You with Coordination Compounds?
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 75-question set is mapped to a sub-topic that still belongs to the current Class 12 Chemistry chapter (now Chapter 5, formerly Chapter 9).
- 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 Coordination Compounds setups almost verbatim, lifting your entrance score for this high-weightage unit.
Coordination Compounds 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 |
|---|---|---|
| IUPAC naming | Single neutral or single anion ligand, simple cation complex | Mixed-ligand complex with ambidentate (NO2-/ONO-) plus charge balance trap |
| VBT hybridisation | Given complex, predict sp3d2 vs d2sp3 | Given magnetic moment, deduce both hybridisation AND ligand field strength |
| Isomerism | Count cis/trans for [Pt(NH3)2Cl2] | Count all geometric + optical isomers for [M(AA)2X2] type |
| CFT | Calculate CFSE for octahedral high-spin | Compare CFSE of two complexes differing only in ligand strength (spectrochemical reasoning) |
2026-27 Syllabus Status of Coordination Compounds Exemplar Problems
The NCERT Exemplar publication was not refreshed when the textbook was trimmed. The chapter number also changed from 9 to 5 in the textbook, but the Exemplar print kept the old "Chapter 9 Coordination Compounds" label. Almost every Exemplar problem still maps to a sub-topic of the current chapter; only a few items touch the trimmed CFT colour/limitations discussion. Skip those during board prep; keep them if you are working the book for JEE Main or NEET.
Detailed kept-trimmed-removed table: see the breakdown on the Coordination Compounds Class 12 Chemistry NCERT Book PDF page.
Why the NCERT Exemplar Matters for JEE Main and NEET Coordination Compounds 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 IUPAC phrasing and bonding-theory reasoning 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 for Coordination Compounds.
- 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 Coordination Compounds attempts from a B1 to an A1, because the chapter is a 7-9 mark slot every year.
JEE Main and NEET Coordination Compounds Questions Inspired by the Exemplar
Recent entrance papers have reused setups from this chapter. The instances below come from the last two sittings of JEE Main and NEET.

Time-per-Question Budget for the Coordination Compounds 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 | 39 | 3 to 5 | ~ 160 min |
| SA, Matching, Assertion-Reason | 31 | 5 to 8 | ~ 200 min |
| LA | 5 | 20 to 25 | ~ 110 min |
| Whole chapter | 75 | - | ~ 8 hours |
Spread the eight-hour load across six to seven sittings; back-to-back LA attempts on isomer drawing cause fatigue and skipped optical-isomer enantiomers.
Coordination Compounds Top Formulae to Memorise Before Attempting the Exemplar
Most Exemplar Coordination Compounds problems hinge on a small set of recurring expressions. Lock these five into memory before opening the PDF; you will save 30 to 40% of attempt time.
| Concept | Formula |
|---|---|
| Spin-only magnetic moment | μ = √[n(n+2)] BM, where n = unpaired electrons |
| CFSE for octahedral complex | CFSE = (-0.4 nt2g + 0.6 neg) Δo |
| Tetrahedral vs octahedral splitting | Δt = (4/9) Δo |
| Effective Atomic Number (EAN) | EAN = Z - oxidation state + 2 × coordination number |
| Stepwise to overall stability constant | βn = K1 × K2 × ... × Kn |

Coordination Compounds Class 12 Chemistry NCERT Exemplar Book PDF FAQs
Ques. Where can I download the Coordination Compounds Class 12 Chemistry NCERT Exemplar Book PDF?
Ans. You can download the Coordination Compounds Class 12 Chemistry NCERT Exemplar Book PDF directly from this page. Both the Normal and HD versions are available, and both are free.
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 and renumbered. The Exemplar still labels the chapter as "Chapter 9 Coordination Compounds", but the content maps directly to the new Chapter 5 in the 2026-27 textbook. A small minority of problems touch the trimmed CFT colour/limitations content and can be skipped during board preparation.
Ques. Why does the Exemplar call it Chapter 9 while the new textbook says Chapter 5?
Ans. The Exemplar publication still follows the legacy pre-rationalisation chapter numbering. The 2026-27 textbook collapsed 16 chapters into 10, so what used to be Chapter 9 Coordination Compounds is now Chapter 5. The chapter content is the same; only the chapter number differs between the two books.
Ques. How many pages is the Class 12th Chemistry Chapter 5 Exemplar Book PDF?
Ans. The Coordination Compounds Exemplar PDF runs approximately 20 pages and packs 75 HOTS problems across MCQ-I, MCQ-II, SA, Matching, Assertion-Reason, and LA types.
Ques. How many problems does the Coordination Compounds chapter of the Exemplar contain?
Ans. The chapter holds 75 problems in total, split as MCQ-I (25), MCQ-II (14), SA (22), Matching (4), Assertion-Reason (5), and LA (5).
Ques. Are Coordination Compounds 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 Coordination Compounds in 5 of the last 5 board papers (the chapter is too high-weightage to skip). For an A1 grade in Chemistry, working the Exemplar for this chapter is practically required.
Ques. Where can I find the solutions to the Coordination Compounds Exemplar problems?
Ans. Worked answers for every problem in this chapter are on the Coordination Compounds Class 12 Chemistry NCERT Exemplar Solutions page.
Ques. How long does it take to finish the Coordination Compounds chapter of the Exemplar Book?
Ans. Plan for around 8 hours spread across six to seven sittings: roughly 2.5 hours for the MCQ-I and MCQ-II types, around 3.5 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 Coordination Compounds preparation?
Ans. Yes, this is the single highest-yield NCERT publication for the chapter in entrance exams. JEE Main 2024 and 2025 each carried at least three Coordination Compounds questions whose setups mirrored Exemplar problems (CFSE comparison, hybridisation from magnetic moment, isomer counting). NEET also reuses Exemplar MCQ-II patterns on spectrochemical series and pi back-bonding in carbonyls.
