Amines contain a basic nitrogen atom with a nonbonding electron pair shown (the electron-dense elongated balloon) in the figure below. Amines are classified according to the number of substituents (R Groups) that are attached to the Nitrogen atom-Numbering up to 3. In primary amines, there is one substituent, called R1, while disubstituted or secondary amines are designated R2. While an R3 group is a called a Tertiary Amine.
