Help determining order of basicity of amines: (possibly could be explained using substitution, resonance, and hybridization effects)?
a) Why is Ph-NH2 LESS basic than NH3?
b) Why is p-nitroaniline LESS basic than aniline?
c) Why is pyridine MORE basic than aniline?
d) Why is 3-nitropyrrole LESS basic than pyrrole which is LESS basic than imidazole?
