In lecture, did Lavelle say that acids are stronger or weaker when they have resonance?

Those with resonance structures are weaker acids because it is harder for the hydrogen atoms to "break off" because the negative formal charge is distributed throughout so resonance structures are more stable.

It really depends on if the conjugate base is stable (forming a Stronger acid) or unstable (forming a weak acid). I don't think there is a single rule that works all the time.

Acids with resonance are stronger because resonance stabilizes the anion by withdrawing electron density and spreading out the charge.

Acids are stronger when there is resonance because the electrons are delocalized, in which the charges would be spread out more.
