Why the NCERT Exemplar Matters for JEE Main and NEET Amines Prep
The NCERT Exemplar is the official publication paper-setters reference when designing HOTS problems for CBSE, JEE Main, and NEET. Three reasons it earns a slot in your plan:
- Same author body: The Exemplar trains you on the exact mechanism and basicity-reasoning phrasing CBSE markers expect.
- Six question types: MCQ-I, MCQ-II, SA, Matching, Assertion-Reason, and LA in one book matches today's CBSE paper and JEE Main multiple-correct style.
- Free and offline: Works on a phone with no reader app; no private question bank needed.
Boards toppers cite the Exemplar as the single book that lifted their organic-nitrogen attempts from a B1 to an A1.

Amines NCERT Exemplar Question-Type Breakdown
The 2026-27 Exemplar print splits Chapter 9 (legacy Chapter 13) 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) | 27 | 1 |
| MCQ-II (one or more correct) | 10 | 2 |
| Short Answer (SA) | 28 | 2 to 3 |
| Matching Type | 2 | 3 |
| Assertion and Reason | 7 | 1 |
| Long Answer (LA) | 3 | 5 |
| Total | 77 | - |
MCQ-II is the most-failed type in this chapter because the trap usually lives in distinguishing Gabriel synthesis from Hofmann bromamide for a target 1° amine, or in spotting which reagents preserve vs cleave an N-acetyl protecting group.
What's Inside the Amines Class 12 Chemistry Exemplar PDF
The Exemplar runs about 22 pages and packs the 77 problems into six question-type sections. The topic map tells you where each sub-topic is concentrated.

| Electrophilic substitution on aniline and protection by acetylation | Q 6, 17, 20, 27, 59, 60, 61, 62, 63, 64, 65 |
| Matching reagents to amines / functional-group conversions | Q 66, 67 |
Amines Exemplar vs NCERT Textbook: Difficulty Comparison
The Exemplar twists setups you have already met in the textbook. The shift is one of three kinds, shown below.
| Setup | NCERT Textbook | Exemplar Twist |
|---|---|---|
| Basicity ordering | Compare CH3NH2 with NH3 and aniline in water | Order five amines including a benzyl amine and a cyano-substituted amine, balancing inductive and resonance contributions |
| Diazonium route | Single conversion from aniline to chlorobenzene | Multi-step conversion from benzene to a meta-disubstituted product using acetylation protection plus Sandmeyer |
| Hinsberg test | Distinguish 1° from 2° from 3° amine | Predict the appearance and KOH-solubility of the sulphonamide product for each of three amines in one mixed sample |
| Hofmann bromamide degradation | RCONH2 → RNH2 with one-carbon loss | Identify which amide will fail the degradation due to alpha-halogenation interference, and explain |

Amines Top Reactions to Memorise Before Attempting the Exemplar
Most Exemplar problems hinge on a small set of recurring named reactions. Lock these five into memory before opening the PDF.
| Concept | Reaction / expression |
|---|---|
| Gabriel phthalimide synthesis (1° amine only) | C6H4(CO)2NK + R-X → phthalimide intermediate → R-NH2 (NaOH / H2O) |
| Hofmann bromamide degradation (1-C loss) | RCONH2 + Br2 + 4 KOH → RNH2 + K2CO3 + 2 KBr + 2 H2O |
| Diazotisation of aromatic 1° amine | ArNH2 + NaNO2 + 2 HCl → ArN2+Cl- (273-278 K) |
| Sandmeyer reaction | ArN2+X- + CuCl/HCl → ArCl + N2 (similar with CuBr/HBr, CuCN/KCN) |
| Azo coupling with phenol | ArN2+X- + C6H5OH → p-Ar-N=N-C6H4OH (NaOH, 0-5°C) |

Amines Class 12 Chemistry NCERT Exemplar Book PDF FAQs
Ques. Where can I download the Amines Class 12 Chemistry NCERT Exemplar Book PDF?
Ans. You can download the Amines 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 "Unit 13 Amines", but the content maps directly to the new Chapter 9 in the 2026-27 textbook. A small minority of problems touch the trimmed biological-amines pharmacology and can be skipped during board preparation.
Ques. Why does the Exemplar call it Chapter 13 while the new textbook says Chapter 9?
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 13 Amines is now Chapter 9. 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 9 Exemplar Book PDF?
Ans. The Amines Exemplar PDF runs approximately 22 pages and packs 77 HOTS problems across MCQ-I, MCQ-II, SA, Matching, Assertion-Reason, and LA types.
Ques. How many problems does the Amines chapter of the Exemplar contain?
Ans. The chapter holds 77 problems in total, split as MCQ-I (27), MCQ-II (10), SA (28), Matching (2), Assertion-Reason (7), and LA (3).
Ques. Are Amines 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 this chapter in 4 of the last 5 board papers. For an A1 grade in Chemistry, working the Exemplar for this chapter is practically required.
Ques. Where can I find the solutions to the Amines Exemplar problems?
Ans. Worked answers for every problem in this chapter are on the Amines Class 12 Chemistry NCERT Exemplar Solutions page.
Ques. How long does it take to finish the Amines chapter of the Exemplar Book?
Ans. Plan for around 7 to 8 hours spread across six to seven sittings: roughly 2.5 hours for the MCQ-I and MCQ-II types, around 4 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 Amines 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 one Amines question whose setup mirrored Exemplar problems (basicity ordering across substituted anilines, Hinsberg discrimination, Sandmeyer product prediction). NEET also reuses Exemplar Assertion-Reason patterns on aniline electrophilic substitution and Gabriel synthesis limitations for aromatic amines.
