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
