### Exercise 2: Identification of Acidic α-Hydrogens in Compounds

**Question:**  
In the following compounds, tell how many acidic "α-H's" there are in each.

**Compounds to Analyze:**
1. Benzaldehyde (C₆H₅CHO)
2. Ethyl Acetate (CH₃COOCH₂CH₃)
3. Acetone (CH₃COCH₃)
4. Cyclopentanone (C₅H₈O)
5. Formaldehyde (CH₂O)
6. Ethyl Acetoacetate (CH₃COCH₂COOCH₂CH₃)

**Graphs/Diagrams:**

1. **Compound 1:** Benzaldehyde (C₆H₅CHO)
   ![Benzaldehyde](Your_Image_URL_Here)

   - Structure: A benzene ring (C₆H₅-) attached to a formyl group (-CHO)
   - Acidic α-Hydrogens to Consider: 0 (The formyl group does not have adjacent hydrogens)

2. **Compound 2:** Ethyl Acetate (CH₃COOCH₂CH₃)
   ![Ethyl Acetate](Your_Image_URL_Here)

   - Structure: CH₃ attached to a carbonyl group (CO) and an ethoxy group (OCH₂CH₃) 
   - Acidic α-Hydrogens to Consider: 3 (Hydrogens on the α-Carbon adjacent to the carbonyl group)

3. **Compound 3:** Acetone (CH₃COCH₃)
   ![Acetone](Your_Image_URL_Here)

   - Structure: CH₃ attached to a carbonyl group (CO) and another CH₃ group 
   - Acidic α-Hydrogens to Consider: 6 (Three hydrogens on each of the two methyl groups adjacent to the carbonyl)

4. **Compound 4:** Cyclopentanone (C₅H₈O)
   ![Cyclopentanone](Your_Image_URL_Here)

   - Structure: Five-membered ring with one carbonyl group
   - Acidic α-Hydrogens to Consider: 2 (Hydrogens on the α-carbon atoms adjacent to the carbonyl group)
