Questions & Step-by-Step Solutions

What is the primary product when chlorobenzene is treated with sodium hydroxide at high temperature?
Correct Answer: Phenol
  • Step 1: Start with chlorobenzene, which is a compound made of a benzene ring with a chlorine atom attached.
  • 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 the heating process, the chlorine atom in chlorobenzene is replaced by a hydroxyl group (OH) from sodium hydroxide.
  • Step 5: The result of this reaction is phenol, which is a compound with a hydroxyl group attached to a benzene ring.
