how to do numbering and naming for AMINE compound?

Question

anonymous · Answer

It's the same for any other functional group but with amine at the end instead. The number tells you which carbon the amine group is on. E.g: $$CH _{3}CHNH_{2}CH_{2}CH_{3}\Longleftrightarrow 2-butanamine$$

Amines are named in several ways. Typically, the compound is given the prefix "amino-" or the suffix: "-amine." The prefix "N-" shows substitution on the nitrogen atom. An organic compound with multiple amino groups is called a diamine, triamine, tetraamine and so forth.
Lower amines are named with the suffix -amine.
