Which of the following is the correct method to prepare phenol? (2022)
  • Step 1: Start with chlorobenzene, which is a compound made of a benzene ring with a chlorine atom attached.
  • Step 2: Prepare a solution of sodium hydroxide (NaOH), which is a strong base.
  • Step 3: Heat the chlorobenzene and sodium hydroxide solution together. This process is called hydrolysis.
  • Step 4: During hydrolysis, the chlorine atom in chlorobenzene is replaced by a hydroxyl group (OH), resulting in the formation of phenol.
