NEET 2023 Chemistry Haloalkanes and Haloarenes Questions
Use this page to connect the official 2023 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.
Example 2 · difficulty 2/5
Propene is treated with HBr in the absence of peroxide. What is the major haloalkane formed?
- A. 1-Bromopropane
- B. 1,2-Dibromopropane
- C. 2-Bromopropane
- D. 3-Bromoprop-1-ene
Example 3 · difficulty 2/5
What is a major limitation of preparing higher haloalkanes by direct free-radical halogenation of alkanes?
- A. Alkanes never react with halogens
- B. Only fluoroalkanes can be produced
- C. The reaction always converts carbon atoms into carbon dioxide
- D. A mixture of positional isomers and further substituted products may form
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 2023 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 2023 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.
