Let's analyze each compound based on the given descriptions and determine if they are ionic or molecular.
### Compound 1:
- Description: Clear liquid with a strong pleasantly fruity smell, freezes at about -10°C, and does not conduct electricity in the solid state.
- Analysis:
- The fact that it does not conduct electricity in the solid state suggests it is not ionic, as ionic compounds typically conduct electricity when melted.
- Freezing at a relatively low temperature and having a fruity smell are typical characteristics of molecular compounds.
- Conclusion: Molecular
### Compound 2:
- Description: Hard white smooth odorless solid, insoluble in water, remains hard without softening even after heating for 10 minutes.
- Analysis:
- Hard solids that do not soften when heated and are insoluble in water are often ionic compounds. Ionic compounds typically have high melting points and are hard and brittle.
- Conclusion: Ionic
### Compound 3:
- Description: Yellow-white solid, forms an oily yellow liquid on melting, which is a good electrical insulator.
- Analysis:
- The fact that it forms an oily yellow liquid and is a good electrical insulator in the liquid state suggests it is likely molecular. Ionic compounds generally conduct electricity when in liquid form.
- Conclusion: Molecular
Summarizing our conclusions:
- Compound 1: Molecular
- Compound 2: Ionic
- Compound 3: Molecular
Therefore, the results are:
- Compound 1: Molecular
- Compound 2: Ionic
- Compound 3: Molecular
