Regarding Resonance Structures and Weak Acids

[Sila_Sozeri_1C]

Hi! I was wondering why molecules with resonance are thought to be weak acids as electron delocalization usually stabilizes the structure, but I remember Dr. Lavelle mentioning that it weakens the structure. Any help would be much appreciated!

When discussing resonance and the strength of acids, I think we are discussing the relative acidity of acids. When we are to compare two acids, the one with resonance tends to be stronger as the electrons are delocalized and thus the structure after a proton is lost is more stable; so, it is more likely to lose that proton, and thus it is a stronger acid as it will more readily lose H+.

Molecules with resonance are more stable and therefore stronger acids because that means the ion itself when dissociated is stable.
