Question
**Activity Title: Understanding Bronsted Acidity and Resonance**

**Objective:** Rank the given compounds in order of increasing Bronsted acidity and explain using drawings of each conjugate base anion. Highlight relevant resonance contributors, and include the term "energy of electrons" in your explanation.

---

**Instructions:**

- **Task:** Rank the compounds A, B, and C in order of increasing acidity based on their Bronsted acidity. Ignore keto isomers during this exercise.
  
- **Required Explanation:** Provide a brief explanation for your ranking that includes:
  1. Drawings of each conjugate base anion.
  2. All relevant resonance contributors.
  3. A discussion involving the "energy of electrons."

---

**Rank Order:**

- **Acidity Scale Diagram:**  
  Weakest < Moderate < Strongest

**Compounds to Analyze:**

1. **Compound A:**  
   - Structure: Contains an alcohol (–OH) group attached to a carbon.
   - Other Characteristics: Features a carboxyl group in the molecule.
  
2. **Compound B:**  
   - Structure: Similar backbone with a different positioning of functional groups.
 
3. **Compound C:**  
   - Structure: Features another placement variant of functional groups similar to A and B.

**Guidance for Analysis:**

- **Conjugate Base Anion Drawing:** Illustrate each anion formed after a compound donates a proton.
- **Resonance Contributors:** Show possible resonance structures that stabilize each anion.
- **Energy of Electrons:** Explain how resonance affects the energy stability of electrons in each compound's conjugate base, thus impacting acidity.

--- 

By following these guidelines, students should be able to compare the acidity of the compounds and understand the role of resonance and electron energy in determining acidity levels.

**Additional Resource:** For visual reference, click [here](#) to access an image preview of the structures.

**Conclusion:** This activity allows students to visually interpret chemical structures and understand theoretical concepts in acid-base chemistry via practical examples.

Expert Solution
Step 1: Define Acidity

A bronsted lowry acid donates protons while a bronsted lowry base accepts proton.

Acidity is defined as the ability of a molecule to release protons.  If a compound  easily donates proton it is highly acidic.  it depends on the stability of the conjugate base.


An arrow always depicts from a region of high electron density to low electron density ; that is tail depicts region of high electron density and head depicts region of low electron density.
