Which of the following compounds can be used to distinguish between primary, secondary, and tertiary amines? (2023)

Step 1: Understand what amines are. Amines are organic compounds that contain nitrogen atoms.
Step 2: Know the types of amines. There are three types: primary (1°), secondary (2°), and tertiary (3°) amines.
Step 3: Learn about nitrous acid. Nitrous acid (HNO2) is a chemical that can react with amines.
Step 4: Recognize how nitrous acid reacts with each type of amine. Primary amines react to form a gas (nitrogen), secondary amines form a different product, and tertiary amines do not react significantly.
Step 5: Conclude that by observing the reaction with nitrous acid, you can tell if an amine is primary, secondary, or tertiary.
