Question

Ethyl amine is more basic than aniline. why?

Answer 1

Ethyl amine is more basic than aniline in a subsequent way:

• Ethyl amine is more basic than aniline because, In ethyl amine, an ethyl is an electron-donating group. So, more electrons are accessible around nitrogen for contribution. However, in aniline, the phenyl group is the electron attracting group. Lone pair of electrons on nitrogen is involved in localisation.
• The ethyl group is electron-donating, it improves electron density on nitrogen due to the +I effect. But an aniline phenyl group is an electron-withdrawing group, it reduces the electron density of nitrogen due to the −I effect. Therefore, ethyl amine is more basic than aniline.

Answer 2

Ethylamine is more basic than aniline.

• In ethylamine, ethyl is electron donating group.
• Hence more electrons are available around nitrogen for donation.
• Aniline is aromatic primary amine.
• But in aniline, phenyl group is electron attracting group.
• Lone pair of electron on nitrogen is involved in delocalisation.
• Lone pair of electrons on nitrogen is not readily available for donation,as it is involved in the resonance.
• Ethylamine, also known as ethanamine, is an organic compound.
• It is a colourless gas with strong ammonia-like odor.
• It is a nucleophilic base, as is typical for amines.
• Aniline is an organic compound  consisting of a phenyl group attached to an amino group.
• aniline is the simplest aromatic amine.
• Its main use is in the manufacture of precursors to polyurethane, dyes etc.
• It is colorless oil like flammable liquid with strong odor.

• It is an industrially significant commodity chemical.
