🧠 The Basic Strength Duel
Basicity is the willingness to share a lone pair of electrons. For substituted anilines, any group that pushes electrons into the ring () makes the Nitrogen more "generous" (stronger base). Any group that pulls electrons away () makes it "stingy" (weaker base).

🗺️ The Substituent Effect
1. Compound II (p-nitroaniline): The  group is a powerful electron-withdrawing group (). It pulls the lone pair from Nitrogen deep into the ring, making it have the lowest basic stren
