General behaviour of `O_3` is

Options

A. Gives electrons
B. Gives `O_2`
C. Reaction with `H_2`
D. Accept electrons

Answer

To solve the question regarding the general behavior of ozone (O₃), we can analyze the options provided and understand the properties of ozone.

### Step-by-Step Solution:

1. **Understanding Ozone (O₃)**: Ozone is a triatomic molecule consisting of three oxygen atoms. It is a pale blue gas with a distinct smell and is found in the Earth's stratosphere.

2. **Ozone's Role in the Atmosphere**: Ozone plays a crucial role in absorbing ultraviolet (UV) radiation from the sun. This absorption protects living organisms from harmful UV rays.

3. **Decomposition of Ozone**: When ozone absorbs UV radiation, it can decompose into diatomic oxygen (O₂) and a free oxygen atom (O). The reaction can be represented as:
\[ 2 O_3 \rightarrow 3 O_2 \]
This indicates that ozone can release oxygen molecules.

4. **Evaluating the Options**:
- **Option A (Gives electrons)**: This is not a typical behavior of ozone.
- **Option B (Gives O₂)**: This is consistent with the decomposition of ozone into oxygen.
- **Option C (Reaction with hydrogen)**: While ozone can react with hydrogen, it is not a primary behavior.
- **Option D (Accept electron)**: Ozone can act as an oxidizing agent, but this is not its general behavior.

5. **Conclusion**: Based on the analysis, the general behavior of ozone (O₃) is best described by **Option B (Gives O₂)**, as it releases oxygen upon decomposition.

### Final Answer:
The general behavior of O₃ is that it gives O₂ (Option B).
