Class 12 Chemistry Chapter 10 Haloalkanes & Haloarenes – Important Topics

Haloalkanes and Haloarenes are those hydrocarbons where one of the hydrogen-bonded to the central carbon atom is replaced by a halogen. Some examples of haloalkenes and haloarenes are chloramphenicol, chloroquine, Chlorofluorocarbon, etc.

Haloalkanes

Haloalkanes are made up of aliphatic alkanes.
The halogen atom is attached to the sp³ hybridized carbon atom of alkyl group.
Haloalkanes are saturated organic compounds and are odourless.
Haloalkanes precipitate in SN² substitution reactions.
Example: CH₃Cl (Methyl Chloride) and CH₃CH₂Br (Ethyl Bromide)

Haloarenes

Haloarenes consists of hydrocarbons with aromatic ring where one or more hydrogren is replaced by halogens.
The halogen atom is attached in the sp³ hybridized carbon atom of the alkyl group.
Haloarenes do not precipitate in SN²substitution reactions.
Haloarenes have a sweet odour.
Example: Chlorobenzene, Bromobenzene.
