ACarbon-oxygen double bonds
BCarbon-sulfur bonds
CCarbon-nitrogen bonds
DCarbon-halogen bonds only
Answer & Solution
Correct answer: C. Carbon-nitrogen bonds
1. The stem asks which element, besides carbon and hydrogen, defines the amine functional group.
2. The text states: "Amines are molecules that contain carbon-nitrogen bonds."
3. Carbon-oxygen double bonds define carbonyl-based groups (aldehydes, ketones, acids), and carbon-sulfur or carbon-halogen bonds define entirely different functional families.
4. So amines are specifically defined by carbon-nitrogen bonds.
