What are the names to each of the following amines: #CH_3-NH-CH_2-CH_3# and #(CH_3CH_2)_3N#?

Amines are named using one of two systems.

Typical Names

Alkylamines are the names given to amines, and the alkyl groups are arranged alphabetically.

It's ethylmethylamine, abbreviated as CH₃NHCH₃CH₃.

N is triethylamine (CH₃CH₃)₃.

IUPAC Titles

The IUPAC names become more intricate.

Secondary and tertiary amines that are symmetric

(a) Prior to the name "azane" (NH₃), cite the name of the alkyl groups followed by the numerical prefix "di-" or "tri-".

N is triethylazane, or (CH₃CH₃)₃.

(b) Refer to the alkyl group names R, which should come before "di-" or "tri-" and come after the word "amine" without a pause.

N is triethylamine (CH₃CH₃)₃.

Secondary and tertiary amines that are not symmetric

(a) as azane (NH3) substituted derivatives.

It is (ethyl)(methyl)azane, or CH₃NHCH₃CH₃.

(b) either as secondary amine RNH₂NH or as N-substituted derivatives of a primary amine RNH₃.

It's N-methylethylamine, or CH₃NHCH₃CH₃.

(c) by listing all substituent group names in alphabetical order, with the class name "amine" coming immediately after, without a space between them and the appropriate numerical prefixes.

What is ethyl(methyl)amine? CH₃NHCH₃CH₃

I won't tell you about the other system, which is the CAS system. There is still another system.

1. CH3-NH-CH2-CH3: N-methylethanamine
2. (CH3CH2)3N: Triethylamine
