Is Nitrophenol More Acidic Than Phenol?

p-Nitrophenol, for example, is 500 times more acidic than phenol itself because the negative charge in the phenoxide ion may be delocalized into the nitro group (Fig.

Why is Nitrophenol more acidic than phenol?

The presence of this group in the ortho or para position decreases the electron density in the O? H bond. As a result, it is easier to lose a proton. ... Hence, ortho and para nitrophenols are stronger acids than phenol.

Which is more acidic phenol or o nitrophenol and why?

Alcohols, Phenols and Ethers. Ortho and para nitrophenols are more acidic than phenol. ... The electron withdrawing groups are more effective in increasing the acidic strength at the para-position relative to the ortho position because of greater dispersal of charge on oxygen atom.
