Why is picric acid a stronger acid than carboxylic acids,despite being a phenolic compound?
(N/A) Picric acid is $2,4,6$-trinitrophenol.
It contains three electron-withdrawing $-NO_2$ groups.
The strong inductive $(-I)$ and resonance effects of these groups weaken the $O-H$ bond,facilitating the easy release of the hydrogen ion $(H^+)$.
Additionally,the resulting phenoxide ion is highly stabilized by the resonance effect of the three $-NO_2$ groups,making picric acid a very strong acid.
