NEET 2017 Chemistry Haloalkanes and Haloarenes Questions
Use this page to connect the official 2017 paper with current Chemistry practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
preparation, substitution, elimination and aryl-halide reactivity.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

- A. Chlorobenzene
- B. 1-Chloro-2,4-dinitrobenzene
- C. 1-Chloro-4-nitrobenzene
- D. 1-Chloro-2-nitrobenzene
Example 3 · difficulty 3/5
Optically active (S)-2-bromooctane is treated with NaI in dry acetone. The major product and its stereochemical outcome are:
- A. (S)-2-iodooctane, formed with retention of configuration
- B. a racemic mixture of 2-iodooctane
- C. (R)-2-iodooctane, formed with complete inversion of configuration
- D. (R)-2-iodooctane, formed with retention of configuration
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2017 Chemistry Haloalkanes and Haloarenes PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2017 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
