Organic Compounds with Functional Groups › Haloalkanes and HaloarenesChapter 26Haloalkanes and Haloarenes
Chloroform in an old hospital, the freon in a refrigerator and the DDT once sprayed on fields are all organic compounds with halogen atoms in them. A halogen on a carbon chain or a benzene ring changes how a molecule behaves, and the rules are clear. In this chapter you learn to name these compounds and prepare them, follow substitution and elimination step by step, see why haloarenes behave differently, and weigh the uses of polyhalogen compounds against their harm. It serves the Indian syllabus (NCERT, JEE Main, NEET) and the matching halogenoalkane topics of A-Level, IB and AP.

Haloalkanes: Naming, Bonding and Preparation
What happens when a halogen takes the place of a hydrogen on a carbon chain. Classification and naming of halogen compounds, the polar carbon-halogen bond and the physical properties it explains, and the main ways to prepare haloalkanes. It covers the Indian syllabus (NCERT, NEET, JEE Main) and the matching topic of A-Level, IB and AP.
Nucleophilic Substitution and Elimination Reactions
How a haloalkane reacts, step by step. The SN2 and SN1 mechanisms with their rates and stereochemistry (inversion and racemisation), elimination and Saytzeff's rule, and how to decide which pathway wins. It covers the Indian syllabus (NCERT, NEET, JEE Main) and the halogenoalkane mechanisms of A-Level, IB Higher Level and AP.
