If a compound possesses both an aldehyde () and a primary amine () group, what is the correct IUPAC Amines Chemistry Question

Question

If a compound possesses both an aldehyde ($-CHO$) and a primary amine ($-NH_2$) group, what is the correct IUPAC nomenclature treatment for the amine group?

Answer: B

💡 Solution & Explanation

According to IUPAC priority rules, the aldehyde ($-CHO$) group has a higher priority than the amine ($-NH_2$) group. Therefore, the aldehyde dictates the principal functional group (taking the suffix '-al'), and the amine group is treated as a substituent, named with the prefix 'amino'.
