Question

Ortho nitrophenol and para nitrophenol which is more acidic

Answer 1

Answer:

para nitro phenol is more acidic because in ortho nitrophenol, intramolecular hydrogen bonding between the adjacent hydroxyl and nitro groups significantly affects release of the proton. So, it is a weaker acid compared to para nitrophenol.

Answer 2

Answer:

Para nitrophenol is more acidic than ortho nitrophenol

Explanation:

Because in ortho nitrophenol,

the intramolecular hydrogen bonding between the adjacent hydroxyl and nitro groups affects the release of protons. Thus ortho nitrophenol is weaker than pata nitrophenol
