Question

Which is more Basic p-aminophenol or p-cresol?

Answer 1

p-aminophenol is more basic than p-cresol.
It is due to the presence of electron donating group -NH₂ in the p-aminophenol.
Though -CH₃ too electron donating group , but mesomeric effect of -NH₂ is more pronounced than hyperconjucation through -CH₃ group on phenol.

Answer 2

Answer:

Explanation:

p-Aminophenol Electron-withdrawing substituents make the phenol more acidic, while electron-releasing substituents make the phenol less acidic. p-aminophenol < p-cresol < p-chlorophenol < p-nitrophenol.
