Stronger acids have more stable conjugate bases, so a more electronegative electron-withdrawing atom would stabilize the conjugate base more than a less electronegative electron-withdrawing atom, making the acid with a more electronegative electron-withdrawing atom the stronger acid.
Hi! In Lec #27, Lavelle discussed the properties that make an acid strong or weak. Strong acids lose protons easily, thus they have weaker/longer A-H bonds because the H+ is easier to remove. Additionally, a stronger acid will have a more stable resulting anion as the acid is more likely to lose the H+. If the anion has an atom with more electron-withdrawing (and resonance), it will be more stable and thus a stronger acid. Hope this helps.
stronger acids are more stable after they have lost their H+. If a molecule loses a proton and is stable it is less likely to want to pick one up again and therefore will stay completely deprotenated so that's why a stronger acid will have a more stable conjugate base!
