Lone pair on $N$ accepts $H+$ ions

An alkylammonium salt

$\text{R-NH}_3^+\text{Cl}^-$

Availability of the lone pair on $N$

Increase it via positive inductive effect

$\text{NH}_3$ < 1° < 2° < 3°

Lone pair delocalised into benzene ring

Aromatic < $\text{NH}_3$ < 1° < 2° < 3°

They have a lone pair on $N$ atom

Three alkyl groups give highest electron density
