Chapter 17: Q.1. (page 641)

Question: Draw all possible resonance structures for the antihistamine diphenhydramine, the active ingredient in Benadryl.

Short Answer

Expert verified

Answer

Resonating structures of diphenhydramine.

Step by step solution

01

Resonance structures

Some properties of an organic compound, that cannot be explained by a single structure are explained using multiple structures.

That differs only in the position of πbond or nonbonding electrons are called resonance or canonical structures.

02

Resonance structures for diphenhydramine

Resonating structures are drawn by only moving the πbonds (atoms or groups never change their position).
