Haloalkanes and Haloarenes - Classification

Description:

Haloalkanes and Haloarenes can be classified based on the hybridization state of the carbon atom to which it is attached.

Compounds with sp³ C − X bond

• Alkyl Halides − where the carbon bearing halogen has sp³ hybridization. It can be further into primary, secondary and tertiary depending on the number of carbon atom to which the α − carbon (carbon bearing the halogen atom) is attached.

• Allylic Halides − These are compounds in which the halogen atom is bonded to sp³ − hybridized carbon atom next to a C = C bond. This carbon is referred to as allylic carbon.

• Benzylic Halides − These are compounds in which the halogen atom is bonded to sp³ − hybridized carbon atom next to an aromatic ring.

Compounds with sp² C − X bond

Vinylic Halides and Aryl halides − These are compounds in which the halogen atom is bonded to sp² − hybridized carbon atom of a C = C bond.
