`color{green}(text(Common System ))` : In this, an aliphatic amine is named by prefixing alkyl group to amine, i.e., alkylamine as one word (e.g., methylamine).
`=>` In secondary and tertiary amines, when two or more groups are the same, the prefix di or tri is appended before the name of alkyl group.
`color{green}(text(IUPAC System ))` : In this, amines are named as alkanamines, derived by replacement of ‘e’ of alkane by the word amine.
● For example, `color{red}(CH_3NH_2)` is named as methanamine.
● In case, more than one amino group is present at different positions in the parent chain, their positions are specified by giving numbers to the carbon atoms bearing `color{red}(–NH_2)` groups and suitable prefix such as di, tri, etc. is attached to the amine. The letter ‘e’ of the suffix of the hydrocarbon part is retained. For example, `color{red}(H_2N–CH_2–CH_2–NH_2)` is named as ethane-1, 2-diamine.
`=>` In arylamines, `color{red}(–NH_2)` group is directly attached to the benzene ring. `color{red}(C_6H_5NH_2)` is the simplest example of arylamine.
● In common system, it is known as aniline.
● It is also an accepted IUPAC name.
● While naming arylamines according to IUPAC system, suffix ‘e’ of arene is replaced by ‘amine’.
● Thus in IUPAC system, `color{red}(C_6H_5–NH_2)` is named as benzenamine.
`=>` Common and IUPAC names of some alkylamines and arylamines are given in Table 13.1.
