Why is aniline weaker base than cyclohexylamine?

Solution
In aniline (C6H5NH2), the phenyl group (C6H5) is an electron withdrawing group and therefore decreases electron availability on the nitrogen of - NH2 group and thus makes it a weaker base. In cyclohexylamine, the cyclohexyl group (non-aromatic) is an electron releasing group and thus increases electron density on the nitrogen of - NH2 group and makes it a stronger base than aniline (Inductive effect).
