Key Topics to Revise
1
Classification and Nomenclature
- Classification based on hydrocarbon skeleton: haloalkanes, haloalkenes, haloalkynes, haloarenes
- Classification based on number of halogens: mono, di, tri, polyhalogen compounds
- Monohalogen compounds classified by carbon hybridization and position
2
Preparation Methods
- From alcohols: Most important method using HX, PX₃, or SOCl₂
- From hydrocarbons: Addition of HX to alkenes (Markovnikov's rule)
- Halogen exchange: Finkelstein reaction (R-Cl + NaI → R-I), Swartz reaction (R-Cl + AgF → R-F)
3
Physical Properties
- C-X bonds are polar due to electronegativity difference
- Boiling points: R-I > R-Br > R-Cl > R-F (due to van der Waals forces)
- For same halogen: boiling point increases with chain length
4
Optical Isomerism and Chirality
- Chiral carbon has four different groups attached
- Chiral molecules are non-superimposable on mirror image
- Enantiomers have equal and opposite optical rotation
