WebApr 8, 2024 · Alkylation and Acylation of Benzene This reaction is popularly known as Friedel-Crafts reaction. The reactivity of haloalkanes gradually increases as you move up the periodic table and polarity also increases. This means that the reactivity of an RF haloalkane is maximum followed by the reactivity of RCl then RBr and finally RI. WebJul 22, 2011 · AlCl3 promotes the chlorination of aromatic molecules such as benzene, when chlorine (Cl2) is added. The AlCl3is regenerated, and HCl is a byproduct. Example 2: …
WebBeing so exothermic, a reaction of flourine with benzene is explosive! For iodine, electrophillic iodination is generally endothermic, hence a reaction is often not possible. Similar to bromide, chlorination would require the aid of an activating presence such as Alumnium Chloride or Ferric Chloride. The mechanism of this reaction is the same ...
