Which of the following specific haloarenes can be highly efficiently and cleanly synthesized from a — Haloalkanes and Haloarenes Chemistry Question

💡 Solution & Explanation

A) True. This is the Balz-Schiemann reaction, the primary method for making aryl fluorides. B) True. Iodide is a potent nucleophile; gently warming the diazonium salt with $KI$ easily displaces the $N_2$ group without requiring a copper catalyst. C) True. This is the standard Sandmeyer reaction for aryl chlorides. D) False. Bromine water does not displace the diazonium group; the Sandmeyer ($CuBr/HBr$) or Gattermann ($Cu/HBr$) reaction is strictly required to introduce bromine.
