Amines can be named using two different systems:

 

as alkyl amines (naming the alkyl group or groups attached to the N)

 

as alkanamines (naming the alkane to which the N is attached)

 

Alkanamine : The parent alkane (the longest chain containing the carbon to which the N is attached) is numbered from the end closest to the carbon with the N on it.

 

methyl amine
or
methanamine

isopropyl amine

or

2-propanamine

 
 

 

1-methylbutyl amine

 

or

 

2-pentanamine

 

Secondary amines
 
Alkanamine: The longest chain to which the N is attached is the parent chain. The other group attached to the N is named as an N-alkyl substituent.
 
 
dimethyl amine
or
N-methylmethanamine

 

ethyl methyl amine

 

or
N-methylethanamine

 

1-ethylpropyl-isopropyl amine

 

or

 

N-isopropyl-3-pentanamine
