NEET Chemistry Preparation Methods MCQ Question
Which of the following statements about the preparation methods of haloalkanes and haloarenes is correct?
Alkyl chlorides can be prepared by passing dry hydrogen chloride through alcohol.
Aryl halides can be prepared from aliphatic alcohols by free radical halogenation.
Fluoro compounds are easily prepared by electrophilic substitution methods.
Iodination of arenes does not require an oxidizing agent for the reaction to proceed.
Correct Answer
Detailed Explanation
Alkyl chlorides can indeed be prepared by passing dry hydrogen chloride through alcohol, as stated in the NCERT context. However, aryl halides cannot be prepared through free radical halogenation due to the stability of phenols, and fluoro compounds are not prepared by electrophilic substitution due to the high reactivity of fluorine.
