NEET Chemistry Preparation Methods MCQ Question
Which of the following statements regarding the preparation of haloalkanes and haloarenes is correct?
Aryl halides can be prepared by electrophilic substitution of arenes using bromine in the presence of Lewis acids.
Iodination of arenes is a straightforward process that does not require any oxidising agents.
Haloalkanes can be synthesized from alcohols by direct reaction with hydrogen bromide in the absence of heat.
Free radical halogenation produces a single isomer of haloalkanes regardless of the starting material.
Correct Answer
Detailed Explanation
Aryl halides are indeed prepared by electrophilic substitution of arenes with bromine or chlorine using Lewis acids, as stated in the context. The other options reflect misconceptions about the preparation methods.
