Question
According to IUPAC isomerism classification, what is the specific structural isomeric relationship between propan-1-amine ($1^\circ$ amine) and N-methylethanamine ($2^\circ$ amine)?
Answer: D
💡 Solution & Explanation
In strict IUPAC classification, primary ($1^\circ$), secondary ($2^\circ$), and tertiary ($3^\circ$) amines are formally considered entirely different functional groups. Because the fundamental nature of the functional group changes, they exclusively exhibit Functional Group Isomerism.
