Phenols are the organic compounds that have a benzene ring bonded to a hydroxyl group. We also know them by the name of carbolic acids. They are weak acids and generally form phenoxide ions by losing one positive hydrogen ion (H+) from hydroxyl group.
In earlier days, people were able to synthesise phenol from coal tar. It was a very complex and lengthy process. It had a lot of risks associated with it as well. Nowadays, with advancements in technologies, however, certain new methods have come up for the preparation of phenols in laboratories.
In laboratories, chemists primarily synthesise and derive phenol from benzene derivatives. In this chapter, we will look at some of the ways in which we can produce phenols commercially in laboratories.

Preparation of Phenols from Haloarenes
Chlorobenzene is an example of haloarenes. We can obtain chlorobenzene by the monosubstitution of a benzene ring. When chlorobenzene fuses with sodium hydroxide at 623K and 320 atm, we obtain sodium phenoxide. Finally, sodium phenoxide on acidification gives phenols
