Benzene is prepared in laboratory by distillation of phenol with
Correct answer: B. Zn dust
- A. H_2 O_2
- B. Zn dust
- C. Ethyl bromide
- D. HOCl
Explanation
The preparation of benzene from phenol involves a process called reduction. Zinc dust (Zn) acts as a reducing agent, converting the hydroxyl group (-OH) of phenol into a hydrogen atom (-H). The reaction is typically carried out in the presence of a strong acid, such as concentrated HCl.The overall reaction can be represented as:C_6 H_5 OH + Zn + HCl → C_6 H_6 + ZnCl_2 + H_2 O

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
