Question

explain the methods of preparation of phenol from haloarenes​

Answer 1

Answer:

Chlorobenzene is an example of a haloarene which is formed by the monosubstitution of the benzene ring. When chlorobenzene is fused with sodium hydroxide at 623K and 320 atm, sodium phenoxide is produced. Finally, sodium phenoxide on acidification gives phenol

Answer 2

Explanation:

Chlorobenzene is an example of haloarenes which is made by mono replacement of the benzene ring. When chlorobenzene is reacted with sodium hydroxide at 623K and 320 atm sodium phenoxide is formed. Finally, sodium phenoxide on acidification makes phenols.

Conjugate base: Phenoxide

Solubility in water: 8.3 g/100 mL (20 °C)

Vapor pressure: 0.4 mmHg (20 °C)

Appearance: Transparent crystalline solid

Hope this helps :)
