Class 12 Chemistry Haloalkanes and Haloarenes Classification on basis of compounds containing sp3CX Bond

Classification of halo alkanes and halo arenes on the basis of compounds containing sp3C—X Bond

(a) Alkyl halides or halo alkanes (R—X)

They create a homologous series represented by CnH2n+1X and can be further classified as primary, secondary or tertiary.

(b) Allylic halides

The compounds with halogen atoms bonded to sp3-hybridised carbon to carbon-carbon double bond (C=C) i.e. to an allylic carbon.

(c) Benzylic halides

The halogen atom of these compounds is bonded to sp3-hybridised carbon atom placed next to an aromatic ring.
