    Study Notes

    NCERT Solutions for Class 12 Chemistry Chapter 10: Haloalkanes and Haloarenes

    Introduction

    • The chapter deals with the chemistry of Haloalkanes and Haloarenes
    • The NCERT solutions provided are based on the latest CBSE syllabus (2023-24)

    Nomenclature of Haloalkanes and Haloarenes

    • The IUPAC names of haloalkanes and haloarenes can be determined by identifying the type of halide and its position in the molecule
    • Examples of IUPAC names:
      • 2-Chloro-3-methylbutane (Secondary alkyl halide)
      • 1-Bromo-3,3-dimethyl-1-phenylbutane (Secondary benzyl halide)
      • 1-Chloro-4-(2-methylpropyl)benzene (Aryl halide)

    Structures of Organic Halogen Compounds

    • The structures of organic halogen compounds can be written based on their IUPAC names
    • Examples of structures:
      • 2-Chloro-3-methylpentane
      • p-Bromochlorobenzene
      • 1-Chloro-4-ethylcyclohexane

    Physical Properties of Haloalkanes and Haloarenes

    • Dipole moments of haloalkanes and haloarenes depend on their molecular structure
    • Examples of dipole moments:
      • CCl4: zero dipole moment due to symmetrical structure
      • CHCl3: small dipole moment (1.08 D) due to opposition of dipole moments
      • CH2Cl2: higher dipole moment due to strengthening of dipole moments
