P - nitrophenol is more acidic than phenol. Explain.

Text Solution

Verified by Experts

In p - nitrophenol, the electron - attracting - `NO_(2)` group by its stronger -R effect and relatively weaker -I effect more positively polarised compared to the oxygen atom of phenol. As a result, the O - H bond in p nitrophenol dissociates more easily to give `H^(oplus)` ions. For this reason, p - nitrophenol is more acidic than phenol.
