Questions & Step-by-Step Solutions
What is the boiling point trend among amines? (2020)
Step 1: Understand that amines are organic compounds that contain nitrogen.
Step 2: Recognize that the boiling point of a substance is influenced by its molecular structure and intermolecular forces.
Step 3: Identify that amines can form hydrogen bonds due to the presence of nitrogen, which affects their boiling points.
Step 4: Note that primary amines have higher boiling points than secondary and tertiary amines because they can form more hydrogen bonds.
Step 5: Understand that the presence of alkyl groups can also influence boiling points; larger alkyl groups can increase boiling points due to increased van der Waals forces.
Step 6: Conclude that the boiling point trend among amines is that primary amines generally have the highest boiling points, followed by secondary amines, and then tertiary amines.
