Explain why carboxylic acids are stronger acids than phenols?

Answer»

Solution :Carboxylate ion is more stable due to symmetrical resonating structure (equivalent) . So carboxylate ion is a weak base and carboxylic acid is STRONGER acid.

PHENOXIDE ion is also stabilised due to RESONANCE and has non-equivalent resonance structures.

With negative charge spreading to less ELECTRONEGATIVE CARBON , phenoxide ion is less stable than carboxylate ion .
