Questions & Step-by-Step Solutions

What is the product of the Friedel-Crafts acylation of benzene with acetyl chloride (CH3COCl)?
  • Step 1: Start with benzene, which is a ring of six carbon atoms with hydrogen atoms attached.
  • Step 2: Introduce acetyl chloride (CH3COCl), which has a carbon atom bonded to a carbonyl group (C=O) and a chlorine atom.
  • Step 3: Use a Lewis acid catalyst, such as aluminum chloride (AlCl3), to help the reaction occur.
  • Step 4: The Lewis acid activates the acetyl chloride, making it more reactive.
  • Step 5: The activated acetyl chloride reacts with benzene, replacing one hydrogen atom on the benzene ring with the acetyl group (C=O and CH3).
  • Step 6: The result of this reaction is acetophenone, which has a benzene ring attached to a carbonyl group and a methyl group.
