Question

Take alkyl name of chain & ends in "-amine"

Begins with "amino-" (if paired w/ other functional group that alters ending)

Has a terminal N group

Answer 1

Amines are named by listing the alkyl groups attached to the nitrogen in alphabetical order, with di- or tri- prefixes as needed, and ending with 'amine'. In complex molecules, the amino group is a substituent named with 'amino-'. The IUPAC system may modify the root alkane name ending with 'amine' for systematic names.

Step-by-step explanation:

The naming of amines in organic chemistry follows specific rules based on the structure of the molecule. For simple aliphatic amines, one must:

• List the alkyl groups attached to the nitrogen atom in alphabetical order.
• If there are multiples of the same alkyl group, use prefixes such as 'di-' or 'tri-'.
• End the name with the suffix '-amine'.

If an amine has other functional groups or if its structure is more complex, the amino group (NH₂) is treated as a substituent and is preceded with 'amino-' in combination with the name of the rest of the molecule.

For example:

• ethyl(methyl)amine - An amine with an ethyl and a methyl group attached to nitrogen.
• N-methylethanamine - A name indicating the longest chain is ethane, with a methyl group attached to the nitrogen (N).

Remember, the IUPAC naming system often replaces the final 'e' of the root alkane name with 'amine'. So, methane becomes methanamine when an amine group is attached to it.

Amines are also classified into primary, secondary, and tertiary based on the number of hydrocarbon groups attached to the nitrogen atom.
