Haloalkanes and Haloarenes


1. Alkyl or aryl halides are classified as mono, di or polyhalite compounds. They are polar in nature.

2. Haloalkanes are prepared by the electrophilic addition of halogen acids with alkenes.

3. Haloalkanes are also prepared by the reaction of alcohols with halogen acids, phosphorus halides and thionyl chloride.

4. Aryl halides or haloarenes are prepared by electrophile substitution of arenes. Fluorides and iodides are best prepared by the halogen exchange method.

5. Haloalkanes participate in S-reactions due to polar C-X bond

6. Reactivity order of haloalkanes in S2 reactions: Primary > Secondary > Tertiary

7. Reactivity order of haloalkanes in S1 reactions: Primary < Secondary < Tertiary

8. Optical isomerism in these compounds is found due to the presence of chiral carbon atoms.

9. SN2 mechanism leads to inversion of configuration in haloalkanes whereas the SN1 mechanism leads to racemization.

10. Haloarenes are less reactive towards nucleophilic substitution reactions as compared to haloalkanes.

11. Melting point of p-dichlorobenzene is higher than that of o- and m-isomers. The reason is its symmetry.

12. Halogenation of benzene proceeds by electrophilic substitution mechanism.

13. Polyhalogen compounds have various industrial applications.

14. Chloroform is not used as an anaesthetic due to its toxic nature (formation of phosgene gas).
