Questions & Step-by-Step Solutions

What is the main product when chlorobenzene is treated with sodium hydroxide at high temperature?
  • Step 1: Start with chlorobenzene, which is a benzene ring with a chlorine atom attached to it.
  • Step 2: Prepare sodium hydroxide (NaOH), which is a strong base.
  • Step 3: Heat the mixture of chlorobenzene and sodium hydroxide to a high temperature.
  • Step 4: During heating, the sodium hydroxide acts as a nucleophile, attacking the carbon atom that is bonded to the chlorine in chlorobenzene.
  • Step 5: The chlorine atom is replaced by a hydroxyl group (OH), resulting in the formation of phenol.
  • Step 6: The main product of this reaction is phenol.
