Question

how do the molecular structures and properties of oxygen, o₂, and ozone, o₃, compare?

1. they have different molecular structures and the same properties
2. they have different molecular structures and different properties.
3. they have the same molecular structure and the same properties.
4. they have the same molecular structure and different properties.

Explanation:

Oxygen ($\ce{O2}$) has a linear molecular structure with a double bond, while ozone ($\ce{O3}$) has a bent structure with resonance. Different molecular structures lead to different properties (e.g., $\ce{O3}$ is more reactive, a stronger oxidizing agent, and has a distinct odor compared to $\ce{O2}$). So they have different molecular structures and different properties.

Answer:

1. They have different molecular structures and different properties.
