This chapter covers the structure, properties, preparation, and reactions of haloalkanes and haloarenes, which are key classes of organic compounds containing halogen substituents. It is a core topic in Class 12 chemistry, essential for competitive exam aspirants and undergraduate learners, forming the foundation for understanding substitution, elimination, and coupling reactions.
In this section, you will study:
Classification and nomenclature of haloalkanes and haloarenes
Nature of the carbon–halogen bond and its reactivity
Preparation methods of haloalkanes and haloarenes
Physical and chemical properties
Nucleophilic substitution reactions (SN1 and SN2 mechanisms)
Elimination reactions and competition with substitution
Reactions of haloarenes and their relative reactivity
Uses, environmental effects, and safety considerations
NCERT-aligned explanations, reaction mechanisms, MCQs, and exam-oriented questions
The content is structured to build mechanistic understanding, enhance reaction analysis skills, and prepare students for school examinations, NEET, JEE, and undergraduate assessments.
Develop a strong command over haloalkanes and haloarenes to confidently analyze reaction pathways, predict products, and solve mechanism-based organic chemistry problems.
