How is phenol converted to benzene through reduction with heated zinc dust?

Options

  1. ABy heating in the presence of a strong acid
  2. BBy electrolysis
  3. CBy passing phenol vapors over heated zinc dust
  4. DBy treating with concentrated sulfuric acid

Correct answer

C. By passing phenol vapors over heated zinc dust

Step-by-step solution

Phenol can be reduced to benzene by passing its vapors over heated zinc dust, which causes the removal of the oxygen atom from the phenol molecule, converting it into benzene.
