NEET Chemistry Nomenclature MCQ Question
Which of the following statements about the nomenclature of haloalkanes and haloarenes is correct?
Aryl halides are named by using the prefixes ortho, meta, and para for all types of substitution.
Alkyl halides in IUPAC nomenclature are referred to as halosubstituted hydrocarbons.
Common names for alkyl halides are derived from the halide name followed by the alkyl group.
Vinylic halides have halogen atoms bonded to sp3-hybridised carbon atoms.
Correct Answer
Detailed Explanation
In the nomenclature of haloalkanes and haloarenes, alkyl halides are indeed named as halosubstituted hydrocarbons according to the IUPAC system. Aryl halides use ortho, meta, and para prefixes only for dihalogen derivatives, and vinylic halides are characterized by halogens bonded to sp2-hybridised carbon atoms, not sp3.
