Question
Chapter 17, Problem 17.1P
Interpretation Introduction
Interpretation: All possible resonance structures for the antihistamine diphenhydramine are to be drawn.
Concept introduction: Resonance structure is a blend of two or more Lewis structures. Resonance structures are represented by a double headed arrow between the structures.
Expert Solution & Answer
Answer to Problem 17.1P
All possible resonance structures for the antihistamine diphenhydramine are,
Explanation of Solution
The given structure of antihistamine diphenhydramine is shown below.
Figure 1
The given structure contains oxygen and nitrogen atoms and these atoms are not conjugated with any double bond. Thus, the lone pairs of these atoms do not participate in the resonance. Hence, possible resonance structures for the antihistamine diphenhydramine are shown below.
Figure 2
Conclusion
All possible resonance structures for the antihistamine diphenhydramine are shown in Figure 2.
