Question

According to IUPAC, what is the name of `CH_3CH_2CH_2CH_2`-`NH-CH_2CH_2CH_2CH_3`?

Answer 1

The two acceptable IUPAC names for CH₃CH₂CH₂CH₂NHCH₂CH₂CH₂CH₃ are dibutylazane and dibutylamine.

This amine is a symmetrical amine with general formula R₂NH.

Rule 1

A symmetrical secondary amine R₂NH may be named by citing the name of the substituent group R, preceded by the numerical prefix "di-", as a prefix to the name of the parent hydride "azane".

The R group is butyl, so the name is dibutylazane.

Rule 2

A symmetrical secondary amine R₂NH may be named by citing the name of the substituent group R, preceded by "di-" and followed directly, without a space, by the name "amine".

According to this rule, the name is dibutylamine.
