WebMar 12, 2024 · The aryl group is electron withdrawing in nature, so as the no.of of aryl groups increase, the acidity increase while C H X 3 being electron donating in nature leads to +I effect and thus to basic strength.. That's why … 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.)
