Benzene is formed when Na reacts with which of the following?

Correct answer: D. Phenol

  • A. Alcohol
  • B. Butyl alcohol
  • C. Propanol
  • D. Phenol

Explanation

Phenol is an organic compound that consists of a benzene ring (C6H6) with a hydroxyl group (-OH) attached to it. When sodium reacts with phenol, it undergoes a substitution reaction known as the Kolbe-Schmitt reaction. In this reaction, sodium replaces the hydroxyl group of phenol, resulting in the formation of sodium phenoxide. The sodium phenoxide then undergoes decarboxylation to yield benzene.
