NCERT Solutions for Class 12 Chemistry chapter 10 Haloalkanes and Haloarenes-

Class 12 chemistry chapter 10 deals with haloalkanes and haloarenes and carries Four marks in the CBSE board exam. In this chapter, we will learn IUPAC nomenclature of haloalkanes and haloarenes, important methods of preparation for these compounds, chemical and physical properties of organohalogen compounds and its uses.  In this chapter, there are 22 questions in the exercise. The NCERT Solutions for Class 12 Chemistry chapter 10 Haloalkanes and Haloarenes are designed and explained by chemistry experts to help students. These NCERT solutions help students in their preparation of CBSE Board exams as well as in competitive exams like JEE, NEET, BITSAT etc.

The seven sub-topics of NCERT Class 12 Chemistry chapter 10 Haloalkanes and Haloarenes covers important concepts like IUPAC nomenclature and preparation of haloalkanes and haloarenes and discuss how to use stereochemistry as a tool in the understanding the reaction mechanism and applications of organo-metallic compounds. At the end of the chapter, the environmental effects of polyhalogen compounds also highlighted. Halogenated compounds remain in the environment due to their resistance to breakdown by the bacteria in the soil.

Some important basic points of the Chapter 10 Haloalkanes and Haloarenes-

  • The replacement of one or more than one H-atom in an aliphatic hydrocarbon by halogen atoms results in the formation haloalkane or alkyl halide and the replacement of H-atoms in an aromatic hydrocarbon by halogen atoms results in the formation of haloarene or aryl halide.
  • In haloalkanes, halogen atoms attached to the SP^{3} hybridised carbon atom of an alkyl group.
  • in haloarenes, halogen atoms attached to the SP^{2} hybridised carbon atoms of an aryl group.
