MP Board · Class 12 · Chemistry · Aldehydes, Ketones and Carboxylic AcidsCarboxylic acids are more acidic than alcohols and phenols because:
Step-by-Step Solution
Carboxylate ions are resonance-stabilized with equivalent canonical structures, whereas alkoxide ions are not stabilized by resonance. This makes the release of a proton easier in carboxylic acids.
