Q: Which of the following statements about aromatic amines is true?
Solution: Aromatic amines are less basic than aliphatic amines due to resonance stabilization of the lone pair on nitrogen.
Steps: 7
Step 1: Understand what aromatic amines are. They are amines where the nitrogen atom is attached to an aromatic ring (like benzene).
Step 2: Understand what aliphatic amines are. They are amines where the nitrogen atom is attached to carbon atoms that are not part of an aromatic ring.
Step 3: Learn about basicity. Basicity refers to how well a substance can accept protons (H+ ions). The more basic a substance, the more likely it is to accept protons.
Step 4: Know that nitrogen in amines has a lone pair of electrons that can be used to accept protons.
Step 5: In aromatic amines, the lone pair of electrons on nitrogen can be involved in resonance with the aromatic ring. This means the electrons are shared and not as available to accept protons.
Step 6: In aliphatic amines, the lone pair is not involved in resonance, making it more available to accept protons.
Step 7: Conclude that because of resonance stabilization in aromatic amines, they are less basic than aliphatic amines.
