Draw both resonance structures of the auction formed by the reaction of the most acidic C-H bond of the compound below with base. Include all valence lone pairs in your answer. For structures having different hydrogens of comparable acidity, assume that the reaction occurs at the less substituted carbon. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate resonance structures suing the doubleheadarrow symbol from the the drop-down menu.
