Amines & Amides

Nomenclature
Secondary and Tertiary amines
• Treat additional branches as a branch on
the nitrogen.
• Base name is based on longest chain that
contains the amine.
• Name other chain as alkyl substituent on
the nitrogen.
• Use N- at front of a branch name
indicates that substituent is on the
nitrogen.
Examples

Nomenclature
Some common names
methyl amine CH 3 -NH 2
dimethyl amine CH 3 -NH-CH 3
