Haloalkanes and Haloarenes — NEET/JEE Questions, Notes & Weightage
Class 12 Organic Chemistry NEET weightage: Medium 30 questions
Covers nucleophilic substitution (SN1 vs SN2), elimination reactions, and the chemistry of haloarenes. SN1-vs-SN2 mechanism comparison (based on substrate, nucleophile, and solvent) is this chapter's single most-tested concept.

Frequently asked questions
What is the most important comparison in this chapter?
SN1 vs SN2 mechanisms — their rate dependence, stereochemistry (racemisation vs inversion), and which substrates favour each — is the dominant NEET/JEE question theme.
Is this chapter linked to Alcohols, Phenols and Ethers?
Yes — both rely on the same substitution/elimination mechanisms, so understanding SN1/SN2 here directly strengthens the next chapter too.
