WebMar 26, 2016 · To determine the strength of a base, you look at the stability of the conjugate acid. Protonating the bottom nitrogen in the imidazole disrupts the aromaticity of the ring, because that nitrogen lone pair is part of the pi system. (Upon protonation, the lone pair is tied up in a bond to hydrogen and can no longer contribute to the aromaticity.)

WebYes, the more stable the conjugate base (A-), the more reactive the acid will be, thereby favoring dissociation. HA ----> H+ + A-. I'm not a fan of using the electronegativity as an example of acidity, as it has more do with the negative charge distribution among the overall size of the anion once the hydrogen dissociates.
