a. The pKa of aniline, pyrrole and pyridine are: 4.62, -4 & 5.2.
1. Draw and name the acids of which these are the pKa.
2. Give the basicity order? List from most to least basic.
3. Explain the basicity order in terms of resonance and inductive (polar) effects and solvation effects.
b. Amides
1. Explain why amides are much less basic than amines.
2. Explain why amides are about as acidic as alcohols.
