Introduction
1.The replacement of hydrogen atom(s) in a hydrocarbon, aliphatic or aromatic, by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene), respectively. 2. Haloalkanes contain halogen atom(s) attached to the sp3 hybridized carbon atom of an alkyl group. 3. Haloarenes contain halogen atom(s) attached to sp2 hybridized carbon atom(s) of an aryl group. 4.Many halogen containing organic compounds occur in nature and some of these are clinically useful. 5.Chlorine containing antibiotic, chloramphenicol, produced by soil microorganisms is very effective for the treatment of typhoid fever. 6.These may be classified as mono, Di, or poly-halogen (tri-,tetra-, etc.) compounds depending on whether they contain one, two or more halogen atoms in their structures.
