Question

explain why p-nitrophenol is a stronger acid then 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 OH bond.

☄As a result, it is easier to lose a proton.

☄Hence, ortho and para nitrophenols are stronger acids than phenol.
