Question

Why o-nitrophenol and p nitrophenol is more acidic than phenol

Answer 1

The nitro-group is an electron-withdrawing group. 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.

Answer 2

the nitro group is an electron withdrawing group .the presence of this group in the ortho or para position decreses the electrons desity in the o . H bond . hence.......... ortho and partho nitrophenol are stronger acids than phenol
