Trimethylamin base
WebAMINES AS BASES. This page looks at the reactions of amines as bases. Their basic properties include the reactions with dilute acids, water and copper (II) ions. It only deals with amines where the functional group is not attached directly to a benzene ring. Aromatic amines such as phenylamine (aniline) are much weaker bases than the amines ... WebBase : Base in chemistry refers to the compounds which can donate electrons to other atoms. So, electron-rich chemical species are mostly bases. The basicity of a compound is influenced by many factors like electronegativity, inductive effect, atomic size and so on. A strong base has the tendency to donate lone pairs easily. Answer and ...
