Benzene is prepared in the laboratory by distillation of phenol with
Correct answer: B. Zn dust
- A. H2O2
- B. Zn dust
- C. Ethyl bromide
- D. HOCl
Explanation
The preparation of benzene from phenol involves a reaction called reduction. This reaction is typically carried out by heating phenol with zinc dust (finely powdered zinc metal). The zinc acts as a reducing agent, removing the oxygen atom from the hydroxyl group (-OH) of phenol, resulting in the formation of benzene.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
