An amine is an organic compound or a functional group that contains a basic nitrogen atom with a lone pair of electrons. They derive from ammonia, in which a carbon-containing substituent has replaced one or more hydrogen atoms. Either one or two or all the three hydrogen atoms are replaced. Based on the number of hydrogen atoms replaced, amines are classified into three: Primary, Secondary and Tertiary amines. Amines are essential nitrogen-containing organic compounds. Our subject expert well explains solved examples based on the basicity of amines, synthesis and reactions undergone by amines. In this chapter, students will be able to understand the nomenclature, properties, and structure of amines.
