**Exercise 3: Identifying the Most Acidic Proton(s) and Resonance Structures**

**Instructions:**

1. **Circle the most acidic proton(s):** Identify and encircle the proton(s) in the molecule presented below that demonstrate the highest acidity.

2. **Draw the corresponding conjugate base:** Illustrate the molecule's structure after the most acidic proton(s) has been removed, showcasing the conjugate base.

3. **Draw additional major resonance contributors:** Provide three significant resonance structures for the conjugate base, indicating electron delocalization that stabilizes the ion.

**Diagram Explanation:**

- **Molecule Structure:** The molecule displayed is a five-membered ring, representing a cyclic organic compound with alternating double and single bonds. The presence of two carbonyl groups (C=O) is noted.

- **Indicated Movement:** Arrows indicate possible delocalization of electrons within the conjugate base, which assists in resonance stabilization.
