This delocalization makes the lone pair less obtainable for protonation and decreases the equilibrium frequent Kb, causing aniline becoming fewer standard. Substituents which have been electron-withdrawing even further minimize basicity by pulling electrons far from nitrogen, while electron-donating groups improve basicity by pushing electrons towards nitrogen.
