Problem 17.1 - Organic Chemistry

Question

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

Step-by-Step Solution

Answer

Answer

Resonating structures of diphenhydramine. 

Step-by-Step Solution Step 1: 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   bond or nonbonding electrons are called resonance or canonical structures.

Step 2: Resonance structures for diphenhydramine

Resonating structures are drawn by only moving the $\mathrm{\pi }$ bonds (atoms or groups never change their position).
