While I-5 did not specifically note s-character, the answer alluded to the double bond -similar to arguments we would observe in comparing alkenes and alkynes: (I5): "since the double bond increases acidity, therefore the N not part of the double bond is more basic. Cuz it is less acidic." Because of the similarities with the acidity of alkene and alkyne arguments, the I-5 response was included in this theme. Because of the prevalence of resonance structures for 300 explaining organic II concepts, we hypothesized fewer organic II would use the s-character.
