FAQs on Question Bank (Solutions): Haloalkanes & Haloarenes - Chemistry Class 12 - NEET

1. What are the main differences between haloalkanes and haloarenes?
Ans. Haloalkanes are alkanes with one or more hydrogen atoms replaced by halogen atoms, while haloarenes are aromatic compounds with a halogen atom attached to the benzene ring.
2. How do haloalkanes and haloarenes differ in terms of reactivity?
Ans. Haloalkanes are more reactive towards nucleophilic substitution reactions due to the presence of a polar carbon-halogen bond, while haloarenes are less reactive and require harsher conditions for substitution reactions.
3. What is the significance of haloalkanes and haloarenes in organic chemistry?
Ans. Haloalkanes and haloarenes serve as important starting materials for the synthesis of various organic compounds, pharmaceuticals, and agrochemicals due to the presence of halogen atoms which impart unique properties to the molecules.
4. How are haloalkanes and haloarenes named according to IUPAC nomenclature?
Ans. In IUPAC nomenclature, haloalkanes are named by replacing the -ane suffix of the parent alkane with -yl halide, while haloarenes are named by adding the prefix fluoro-, chloro-, bromo-, or iodo- to the benzene ring.
5. What are some common reactions of haloalkanes and haloarenes in organic chemistry?
Ans. Common reactions of haloalkanes include nucleophilic substitution, elimination, and reduction reactions, while haloarenes undergo electrophilic aromatic substitution reactions due to the stability of the aromatic ring.
