Why aniline is less basic than methylamine?

Account for the following : (a) (CH_(3))_(2)NH is a stronger base than NH_(3) (b) CH_(3)CH_(2)NH_(2) is more basic than CH_(3)CONH_(2) (c) Aniline is less basic than Ethyl amine (d) On sulphonation of aniline, p-amino benzene sulphonic acid is formed.

Basicity of aniline is less than methyl amine, because-

Aniline is weaker base than ethylamine. Explain the reason.

Explain why aniline is not as basic as ammonia.

Explain why amines are more basic than amides.
