**Chemical Structures Overview**

1. **Structure 1: Propanoic Acid**
   - This molecule features a carboxylic acid group, represented by the formula \( \text{C}_2\text{H}_5\text{COOH} \).
   - The central carbon is bonded to a hydroxyl group (\(-\text{OH}\)) and a double-bonded oxygen (\( \text{O}=\)).

2. **Structure 2: Cyclopentanol**
   - This molecule is a cyclic alcohol, shown as a five-membered carbon ring with a hydroxyl group (\(-\text{OH}\)) attached to one of the carbons.
   - The structural formula is typically represented as \( \text{C}_5\text{H}_{10}\text{O} \).

3. **Structure 3: Hexane**
   - This linear chain consists of six carbon atoms linked together, represented by the formula \( \text{C}_6\text{H}_{14} \).
   - It is a simple alkane with no functional groups or double bonds.

4. **Structure 4: Butylamine**
   - This molecule features a primary amine group (\(-\text{NH}_2\)) attached to a four-carbon alkyl chain.
   - The structural formula is \( \text{C}_4\text{H}_9\text{NH}_2 \).

Each of these chemical structures showcases different functional groups and molecular shapes that form the basis for understanding organic chemistry.

**Activity Instructions: Arrange the Acids**

**Objective:**
Organize the provided acids in order of their pKa values, from lowest to highest.

**Layout:**

1. **Header:** "1st Attempt"
   - This section signals that you are starting your first attempt at arranging the acids correctly.

2. **Instructions:**
   - "Arrange the acids shown from lowest pKa to highest pKa."
   - Focus on identifying and comparing the strength of the acids based on their pKa values.

3. **Interactive Section:**
   - "Question List (4 images)"
   - Action: You need to drag and drop each acid structure into the appropriate sequence based on their pKa.

4. **Chemical Structure Provided:**
   - A depicted chemical structure: a carboxylic acid derivative featuring a central carbon atom double-bonded to an oxygen (O), single-bonded to a hydroxyl group (OH), and connected to two other groups. Note the presence of the functional group, which affects acidity.

**Note:**
This exercise tests your understanding of acid strength and pKa values. Utilize your knowledge of molecular structure and how it influences acidity to complete the task.
