Hi,
The question was asking for the most basic N, and I know that it is CH2NH2 because the lone pair on the N is in an sp3 orbital , which has "less" s character.
Then, I'm just curious now...and I want to know the least basic N. So would I look for the opposite trend of most basic...as in now looking at the one that has the MOSt s character? I drew a diagram and the least basic is the N drawn in red, because it is sp2..and its on the ring with least double bonds. am I correct?
thanks!
