NEET Chemistry Preparation Methods MCQ Question
Which of the following statements about the preparation methods of haloalkanes and haloarenes is correct?
Haloalkanes can be prepared by the free radical halogenation of alkanes, while haloarenes are formed by electrophilic substitution using Lewis acid catalysts.
Haloarenes can be prepared by free radical halogenation of alkenes, while haloalkanes are formed through nucleophilic substitution reactions.
Both haloalkanes and haloarenes can be prepared by the same methods of nucleophilic substitution.
Haloalkanes are formed exclusively by the reaction of alcohols with halogen acids, while haloarenes cannot be prepared by electrophilic substitution.
Correct Answer
Detailed Explanation
Haloalkanes are prepared by free radical halogenation of alkanes and by the reaction of alcohols with halogen acids, while haloarenes are formed by electrophilic substitution using Lewis acid catalysts, as mentioned in the NCERT context.
