p-Nitrophenol is a stronger acid than phenol while p-cresol is a weaker acid. This can be explained as
- — CH3 group decreases the electron density on oxygen of O
— H group making p-cresol a weaker acid
- — NO2 group decreases electron density on oxygen of O
— H group making p-nitrophenol a stronger acid
- — CH3 group increases the electron density on oxygen of O — H group making release of H+ easier
- — NO2 group increases the electron density on oxygen of O — H group making release of H+ easier.
Answer
(B) — NO 2 group decreases electron density on oxygen of O — H group making p -nitrophenol a stronger acid
