Which aryl halides cannot be made by direct halogenation of benzene?
AChlorides and iodides
BFluorides and iodides
CBromides and fluorides
DChlorides and bromides
Answer & Solution
Correct answer: B. Fluorides and iodides
Fluorination is too violent and iodination too reversible, so ArF and ArI are made via diazonium salts.
