Expert Answer
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.
