How do you convert chloro benzene to p-nitro phenol?

Answer 1

I'd do it this way. Use Dow's Process (NaOH) to convert chlorobenzene to phenol. Now, use nitrating mixture to get both o and p- nitrophenol. Fractional distillation should give you what you finally need.

Answer 2

To convert chlorobenzene to p-nitrophenol, the chlorobenzene must first be converted to phenol by hydrolysis using a strong base like NaOH. Then, the phenol can be nitrated using a mixture of concentrated nitric acid and concentrated sulfuric acid to obtain p-nitrophenol.
