Aryl iodide and aryl fluoride

Vedclass · Answer

(D) The correct answer is $D$.Electrophilic substitution of benzene with iodine is a reversible reaction,requiring an oxidizing agent (like $HNO_3$ or $HIO_4$) to remove $HI$ and drive the reaction forward; hence,it is not considered a direct preparation.Fluorination is extremely exothermic and highly reactive,making it difficult to control for direct electrophilic substitution.Therefore,aryl iodide and aryl fluoride cannot be prepared directly by simple electrophilic substitution.
