Haloalkanes and Haloarenes

As part of the organic chemistry syllabus, Haloalkanes and Haloarenes are essential topics for the UP PGT Chemistry exam. These compounds are derivatives of alkanes and arenes, where one or more hydrogen atoms are replaced by halogen atoms (such as fluorine, chlorine, bromine, or iodine). Some name reactions are very important like-  Haloform test, Hunsdieker reaction, Swart reaction, Finkelstein, Frankland Reaction, Coreyes House, Kolbe decarboxylation, Sandmeyer, Gattermann, Balzschiemann resctions.

Haloalkanes

Haloalkanes (or alkyl halides) are compounds where a halogen atom is bonded to an aliphatic carbon chain. Their general formula is R-X, where “R” represents the alkyl group, and “X” is the halogen. Example: Chloromethane (CH₃Cl), where a chlorine atom replaces one hydrogen atom in methane (CH₄). 

Preparation: Haloalkanes can be prepared by halogenation of alkanes or by treating alcohols with halogenating agents like phosphorus trichloride (PCl₃). 

Reactions: Nucleophilic substitution: Haloalkanes undergo nucleophilic substitution, where the halogen is replaced by a nucleophile like OH⁻. Elimination: Under certain conditions, haloalkanes undergo elimination reactions to form alkenes.

Haloarenes

Haloarenes (or aryl halides) are compounds in which a halogen atom is directly bonded to an aromatic ring like benzene. Their general formula is Ar-X, where “Ar” represents the aryl group. 

Example: Chlorobenzene (C₆H₅Cl), where a chlorine atom is attached to a benzene ring. 

Preparation: Haloarenes can be synthesized by electrophilic substitution reactions, where a halogen atom is introduced into the benzene ring using halogens like Cl₂ in the presence of a catalyst.

Reactions: Electrophilic substitution: Haloarenes undergo electrophilic substitution reactions, but the presence of the halogen deactivates the ring towards further substitution. Nucleophilic substitution: Although difficult, haloarenes can undergo nucleophilic substitution under strong conditions like high temperature and pressure.
