This video covers the concepts of identification, nomenclature and classification of amines into primary, secondary, and tertiary amines. • What are Amines? • Amines are organic compounds which are derived from ammonia by replacing one or more hydrogen atoms by organic groupds like alkyl or aryl groups. In amines, the carbon atoms are strongly bonded to the nitrogen atoms. • Types or Classification of Amines • Amines are classified into three types depending upon the number of organic substituents that are attached to the nitrogen atoms. These three types are: • 1. Primary Amines: In these, one of the three hydrogen atoms present in ammonia is replaced by an aromatic or alkyl group. An example of primary amines include Methylamine. • 2. Secondary Amines: In these, two hydrogen atoms of ammonia are replaced with two organic substituents which can be alkyl or aryl groups (or both). An example of secondary amine is Dimethylamine. • 3. Tertiary Amine: In these, all the three hydrogen atoms of the ammonia are replaced by three organic substituents. An example of tertiary amine is Trimethylamine. • Note: There is a fourth type of amine which is called cyclic amines. • The nomenclature of amines is a bit different for primary, scondary, and tertiary amines. This naming of amine types are explained in this video with a few examples. • Identification of Amines • To indentify primary, secondary, and tertiary amines, the umber of organic substituents replacing hydrogen atoms are counted. For example, for an amine R-NH2, 1 hydrogen atom is replaced and so, it is a primary amine. • There is also a chemical test which can be done to identify any amine easily. This test is called Hinsberg test. To learn more about Hinsberg test for identification of amines, check this article - https://byjus.com/chemistry/amines-id...
