**Title: Understanding Solubility with "Like Dissolves Like" Principle**

**Diagram Explanation:**

The diagram shows a grid aimed at helping users understand which compounds are likely to dissolve in which solvents, based on the principle that "like dissolves like." 

**Top Row:**

1. **Compounds:**
   - **Left Box:** 
     - Structure: HO-C(=O)-CH₂-CH₂-OH
   - **Middle Box:** 
     - Structure: CH₃-S(=O)-CH₃
   - **Right Box (Solvents):**
     - Structure: CH₃CH₂OH (Ethanol)

2. **Circles:** There are empty circles which appear to be placeholders for user selection or marking.

**Middle Row:**

1. **Solvent:**
   - Structure: H₂O (Water)

2. **Circles:** Empty circles for selection or marking.

**Bottom Row:**

1. **Solvent:**
   - Structure: CCl₄ (Carbon Tetrachloride)

2. **Compounds:** 
   - Left Box: KCl (Potassium Chloride)
   - Right Box: Empty circle for selection or marking.

**Footer:**

There are buttons labeled "Explanation" and "Check" for users to receive explanations or verify their selections.

**Educational Context:**

This diagram is part of a learning module that teaches students about solubility and polarity. Students are expected to use their understanding of molecular structures and polarity to determine which substances are likely to dissolve in each other.

**Applying Like Dissolves Like**

**For each solute, click the button under the better solvent.**

**Solute:**
The solute is a complex organic molecule with the following structure:
- HO–CH₂–CH–CH–CH–CH–CH₂–OH
- Each central carbon atom is bonded to an -OH group, totaling four hydroxyl groups (-OH). It suggests that the solute is likely a sugar or alcohol.

**Which is the better solvent?**

**Solvent Options:**
1. **H₂O (Water)**
   - Represented with a button to select.
2. **Cyclohexane** 
   - A ring structure with alternating single and double bonds (hexagonal).
   - Hydrogens are bonded to each carbon, indicating a nonpolar organic solvent.

**Instructions:**
Select the button corresponding to the solvent that better dissolves the solute based on the "like dissolves like" principle.

**Additional Features:**
- There is an "Explanation" button for more info.
- A "Check" button to verify the correctness of the choice.

This exercise helps understand solubility by demonstrating that polar solutes dissolve better in polar solvents, while nonpolar solutes dissolve in nonpolar solvents.
