Question

Methylamine is more basic than aniline. Give reason.

✓

Answer

In case of aniline, ione pair in nitrogen atom participate with pi electron in benzene. The electron density in nitrogen become less and aniline act as a less base. In case of methyl amine, the resonance is not possible and $CH _3$ group has $a + I$ effect, which increases the electron density in nitrogen. That's why methyl amine react as a strong base.
