Question

Why is o - Nitro phenol is more acidic than 2 - Methyl phenol ?​

Answer 1

Answer:

In ortho nitro phenol, electron withdrawing nitro group is present in ortho position, the electron density of O − H O-H O−H bond is reduced. This makes removal of proton easy. After deprotonation, o-nitrophenoxide ion is resonance stabilized. Hence, ortho nitrophenol is a stronger acid.
