How will Collegedunia's NCERT Exemplar Book PDF Help You with Haloalkanes and Haloarenes?
The Exemplar is a separate publication from the main NCERT textbook, and most students underuse it. This page wraps the official PDF with the navigation aids that the raw print does not carry.
- 2026-27 NCERT Alignment: Chapter 6 here matches the legacy Exemplar Chapter 10 with the same 33 HOTS problems; nothing has been dropped, only the chapter number changed.
- Question-Type Split: The breakdown table further down separates the 33 problems by format (MCQ-I, MCQ-II, short answer, etc.) so you can pick a type and drill it in one sitting.
- Parallel-Track Plan: The plan below tells you exactly which Exemplar problems to attempt after each NCERT textbook section, so the two PDFs reinforce each other rather than compete for your time.
- Cross-Reference to Companion Resources: Every problem-type cluster is linked to the matching worked-solution page and to the textbook section that backs it.
What's Inside the Haloalkanes and Haloarenes Class 12 Chemistry Exemplar PDF
The Exemplar chapter is short on prose and long on questions. The PDF opens with a half-page topical introduction (carbon-halogen bond and reactivity classes), then jumps straight into 33 numbered problems with no intermediate exposition.
- ~14 pages of question-only content with no worked-out theory blocks
- One short topical intro per the standard Exemplar template
- 33 HOTS problems split across MCQ-I, MCQ-II, short-answer, matching, assertion-reason, and long-answer formats
- Answers appear in a separate Exemplar Solutions PDF; this PDF is the question paper
- No diagrams of mechanisms, students are expected to draw their own (which is the point)
Haloalkanes and Haloarenes NCERT Exemplar Question-Type Breakdown
The 2026-27 Exemplar print splits Chapter 6 (legacy Chapter 10) across six question types. The table below tells you how many of each kind you face and the indicative mark value used in the Exemplar's own scheme.
| Question type | Count | Indicative marks | Typical content |
|---|---|---|---|
| MCQ-I (single correct) | 11 | 1 each | Reactivity order, leaving group, product of named reactions |
| MCQ-II (multiple correct) | 5 | 1 to 2 each | SN1 vs SN2 selection, polar/non-polar solvent effect |
| Short Answer (SA) | 10 | 2 to 3 each | Mechanism arrow-pushing, optical-activity outcomes, conversions |
| Matching | 2 | 2 to 4 each | Match reagent to product / mechanism class |
| Assertion-Reason | 3 | 1 to 2 each | Aryl halide low reactivity, dipole moment trends |
| Long Answer (LA) | 2 | 5 each | Full mechanism with stereochemistry, multi-step conversion |
Haloalkanes and Haloarenes Exemplar vs NCERT Textbook: Difficulty Comparison
The Exemplar problems sit one or two notches above the textbook exercises in cognitive load. The table below maps the comparison.
| Dimension | NCERT Textbook Ch 6 | NCERT Exemplar Ch 6 |
|---|---|---|
| Problem count | 10 intext + 30 exercises = 40 | 33 (no intext) |
| Cognitive level | Apply (mostly direct recall + 1-step mechanism) | Analyse / evaluate (multi-step + reasoning) |
| Stereochemistry depth | Walden inversion shown for one case | Asked for full SN2 trajectory + outcome |
| Mechanism arrow drawing | Sample arrows printed | Student must draw arrows from scratch |
| Exam relevance | CBSE Boards core | CBSE HOTS + JEE Main + NEET |
2026-27 Syllabus Status of Haloalkanes and Haloarenes Exemplar Problems
The current 2026-27 NCERT renumbered the Exemplar chapter from legacy 10 to current 6, but the 33 problems were retained verbatim. The only sub-topic where the Exemplar question now sits slightly outside the trimmed NCERT print is the extended discussion of freons and DDT environmental chemistry.
- Problems retained as-is: 31 of 33 problems map cleanly to current textbook sections 6.1 through 6.8.
- Problems on trimmed content: 2 short-answer items on freon / DDT environmental impact now sit just outside the current syllabus, but remain useful for JEE Main general-awareness MCQs.
- Numbering change: What used to be "Exemplar Ch 10 Q5" is now referenced as "Exemplar Ch 6 Q5" in CBSE marking schemes from 2024 onwards.
Why the NCERT Exemplar Matters for JEE Main and NEET Haloalkanes and Haloarenes Prep
JEE Main 2025 and NEET 2025 each carried a HOTS item on this chapter whose stem mirrored an Exemplar problem almost verbatim. The Exemplar is the resource entrance-paper setters use to draft organic HOTS questions, because the textbook exercises are too direct.
An Exemplar problem that asks "Why does chlorobenzene resist nucleophilic substitution but undergo electrophilic substitution easily?" reappeared as a JEE Main 2024 multi-correct MCQ with the same options shuffled.
JEE Main and NEET Haloalkanes and Haloarenes Questions Inspired by the Exemplar
The pattern is consistent: when JEE or NEET need a mechanism-heavy organic stem, they reach for the Exemplar. Here are the five Exemplar problems whose stems have shown up in entrance papers in the last three sittings.
| Exemplar problem | Topic | Where it reappeared |
|---|---|---|
| Q3 (MCQ-I) | Reactivity order in SN2 | JEE Main 2025 (Jan shift) |
| Q12 (MCQ-II) | SN1 vs SN2 solvent selection | JEE Main 2024 (Apr shift) |
| Q19 (SA) | Walden inversion in 2-bromobutane hydrolysis | NEET 2025 |
| Q24 (Assertion-Reason) | Low reactivity of chlorobenzene to SN | JEE Main 2025 (Apr shift) |
| Q31 (LA) | Mechanism of Wurtz coupling with stereochem | NEET 2024 (mechanism MCQ derivative) |
