In the case of mixed amines, the names of alkyl groups are arranged in alphabetical order. The amines are named as N-substituted derivatives of the largest group of primary amine.Example:
(C2H5)2NCH2CH2CH2CH3 - N, N - diethyl butylamine
In the IUPAC system the amines are considered to be amino derivatives of corresponding alkanes. Therefore, they are called aminoalkanes or alkanamines. These names are obtained either by adding a prefix amino before the name of parent alkane or by replacing 'e' from the name of the parent alkene with suffix amine.Examples:
In case of diamines the ending e of the hydrocarbon name is retained and the suffix diamine is added H2N-(CH2)5-NH2 is 1,5 - Pentanediamine.
When additional functional groups such as -OH or double bond are present in an amine, the prevailing priority order for nomenclature is observed.H2N CH2 CH2 OH 2 - amino ethanol
H2N CH2 CH = CH2 is 2 - propen1 - amine
