    because of the benzene ring attached to it. The benzene ring is electron withdrawing making it a stronger acid (and weaker base) than the electron- donating ethyl groups that are weaker acid (stronger base). Comparing aniline which is an aromatic amine and benzyl amine‚ which is an aliphatic amine‚ benzyl amine or aliphatic amines in general are stronger bases than aromatic amines. Also‚ it is because in aniline‚ the lone pair present in it is involved in resonance with the aromatic benzene making them

    Substituents‚ which are attached to the nitrogen atom instead of the carbon of the chain‚ are designated by a capital N. Aromatic amines belong to specific families‚ which act as parent molecules. For example‚ an amino group (—NH2) attached to benzene produces the parent compound aniline. Basicity of amines Amines are basic because they possess a pair of unshared electrons‚ which they can share with other atoms. These unshared electrons create an electron density around the nitrogen
