NEET Chemistry Nomenclature MCQ Question
Which of the following statements about the nomenclature of haloalkanes and haloarenes is correct?
Vinylic halides have halogen atoms bonded to sp3-hybridised carbon atoms.
Common names for alkyl halides are derived by naming the alkyl group followed by the halide name.
Dihalogen derivatives of benzene use the prefixes o-, m-, and p- in both common and IUPAC naming.
Aryl halides are compounds where the halogen is bonded to a sp3-hybridised carbon of an aromatic ring.
Correct Answer
Detailed Explanation
Statement B is correct as common names for alkyl halides are derived by naming the alkyl group followed by the name of halide. Statement A is incorrect because vinylic halides bond to sp2-hybridised carbons, while statement C is incorrect because the prefixes are only for common names. Statement D is incorrect as aryl halides involve sp2-hybridised carbons.
