Aniline is a weaker base than ethylamine because:

1. lone pair of electrons of N-atom is not freely available for coordination due to resonance than in ethylamine.

2. Its b.p. is higher than that of ethylamine.

3. It does not produce a sufficient concentration of ${\mathrm{OH}}^{-}$ ions in solution.

4. It is insoluble in water while ethylamine is soluble in water.
