Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
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.
