## Investigation of Intermolecular Forces: Ionic vs. Covalent Bonds

Two students conducted an investigation to determine if ionic or covalent bonds have stronger intermolecular forces. They used salt (ionic) and sugar (covalent) and collected the following data:

| Property        | Sugar (Covalent)         | Salt (Ionic)                 |
|-----------------|--------------------------|------------------------------|
| Color           | White                    | White                        |
| Texture, Grain Size | Rough, small grains     | Rough, very small grains      |
| Solubility      | Soluble                  | Soluble                      |
| Melting Point   | Melts easily             | Does not melt                |

**Research Question:**  
Which of the following tests will most help them to infer the strength of intermolecular forces between ionic and covalent compounds?

- Color
- Texture, grain size
- Solubility in water
- Melting point

**Analysis:**  
Consider which properties and tests effectively distinguish between the two types of bonding strengths to infer conclusions about their intermolecular forces.
