Why is aniline intrinsically a significantly weaker thermodynamic base than aliphatic amines or stan — Amines Chemistry Question

💡 Solution & Explanation

In aniline, the unshared lone pair of electrons on the nitrogen atom is heavily delocalized into the adjacent $\pi$ -system of the benzene ring through resonance. This physical delocalization drastically reduces the electron density at the nitrogen center, making the lone pair far less available for protonation.
