2 Classification of Haloalkanes and Haloarenes Compounds Containing sp 3 C—X Bond Alkyl halides or haloalkanes (R— X) Allylic halides Benzylic halides Compounds Containing sp 2 C—X Bond Vinylic halides Aryl halides

3 These may be classified as mono, di, or polyhalogen (tri-,tetra-, etc.) compounds depending on whether they contain one, two or more halogen atoms in their structures. For example,

4 They form a homologous series represented by C n H 2n+1 X. Where R’ = Alkyl group Compounds Containing sp 3 C—X Bond Alkyl halides or haloalkanes (R—X)

5 Allylic halides These are the compounds in which the halogen atom is bonded to an sp 3 -hybridised carbon atom next to carbon-carbon double bond (C=C) i.e. to an allylic carbon.

6 Benzylic halides These are the compounds in which the halogen atom is bonded to an sp 3 -hybridised carbon atom next to an aromatic ring.

7 These are the compounds in which the halogen atom is bonded to an sp 2 -hybridised carbon atom of a carbon-carbon double bond (C = C).

8 These are the compounds in which the halogen atom is bonded to the sp 2 -hybridised carbon atom of an aromatic ring.
