Amines

Introduction to Amines
Amines are organic derivatives of ammonia. Amines, like ammonia, are weak bases (Kb = 10?4 to 10?6). This basicity is due to the unshared electron pair on the nitrogen atom.
Amines occur widely in both plants and animals tissues .Nicotine is found in tobacco ;and cocaine is found in the south American coca bush ,Amino acids are the building block from all protein are made and cyclic amine basis are constituents of nucleic acid.
Classification and nomenclature of amines
Amines are classified as primary, secondary, or tertiary based upon the number of carbon-containing groups that are attached to the nitrogen atom. Those amine compounds that have only one group attached to the nitrogen atom are primary, while those with two or three groups attached to the nitrogen atom are secondary and tertiary, respectively.
Amines named
Aliphatic amines are named by naming the alkyl group or groups attached t» nitrogen, and following these by the word -amine. More complicated ones are often named by prefixing amino- (or N-methylamino-y N,N-diethylamino-, etc.) to the name of the parent chain. For example:
