WebA base with many resonance contributors stands to lose more resonance than a base with a lesser number of resonance contributors. Thus a base with many resonance contributors will resist protonation (be a poorer base) than a similar structure with fewer resonance contributors. Acetate ion has two significant resonance contributors, and has more to WebSee Answer Question: Compounds containing nitrogen are often weak bases. One example is aminoethanol, which has the formula HOCH CH3NH, and a value of 3.1x 10-5 2nd attempt Part 1 (1 point) Feedback See Hint Aminoethanol (HOCH2CH2NH3 K - 3.1x 10-is a weaker base than ethylamine (CH3CH2NH2 PK-3.36).
