WebOct 15, 2024 · So, the book proposes that we should treat phenol with $\ce{NaNO2}$ and $\ce{HCl}$ to yield 4-nitrosophenol, and oxidize it to nitrophenol. However, I could not … Webm-Nitrophenol is more acidic than phenol because the nitro group is very electronegative. The polar effect of the nitro substituent stabilizes the conjugate-base anion for the same reason that it would stabilize the conjugate base of an alcohol (Sec. 8.6B). Yet p-nitrophenol is more acidic than m-nitrophenol by more than one pK
Webo-nitrophenol is more volatile due to intramolecular hydrogen bonding. p-nitrophenol is less volatile and has a high boiling point due to intermolecular hydrogen bonding. When phenol is treated with concentrated nitric acid, the nitration results in the formation of 2, 4, 6-trinitrophenol (commonly called picric acid). 2.
