Question

convert chlorobenzene to phenol

Answer 1

Dow's Process is used for this conversion in which chloro benzene is added to sodium hydroxide at 373 K we get phenol and sodium chloride.  The reaction is as follows 

C6H5Cl + NaOH ---> C6H5OH + NaCl

Answer 2

Answer: The conversion is given below in the image.

Explanation:

When chlorobenzene is heated in the presence of concentrated sodium hydroxide (NaOH) at 300°C under high pressure, it results in the formation of sodium salt of phenol which n acidic medium leads to the formation of free phenol. This process is known as Dow's process.

The reaction for the above conversion is given in the image below.
