Carboxylic acids are more acidic than alcohols because:
AThe carboxylate anion is stabilised by resonance over two oxygens
BCarboxylic acids contain more carbon atoms than alcohols always
CThe alcohol O-H bond is much weaker than the acid O-H bond
DAlcohols form hydrogen bonds with water more easily than acids
Answer & Solution
Correct answer: A. The carboxylate anion is stabilised by resonance over two oxygens
In -COO$^-$, the negative charge is delocalised over two equivalent O atoms by resonance, making the anion (and hence the acid) more stable.
