Identify the wrong statements in the following:

Options

A. Oxides of nitrogen in the atmosphere can cause the depletion of ozone layer
B. Ozone absorbs the intense ultraviolet radiation of the sun
C. Depletion of ozone layer is because of its chemical reactions with chlorofluoro alkanes
D. Ozone absorbs infra red radiations

Answer

To identify the wrong statements from the given options, we will analyze each statement one by one.

### Step 1: Analyze Statement 1
**Statement 1:** "Oxides of nitrogen in the atmosphere can cause depression of ozone."

- **Explanation:** This statement is correct. Nitrogen oxides (NOx) can indeed lead to the depletion of the ozone layer. They react with ozone (O3) in the stratosphere, resulting in the formation of nitrogen dioxide (NO2) and oxygen (O2), which contributes to ozone depletion.

### Step 2: Analyze Statement 2
**Statement 2:** "Ozone absorbs the intense ultraviolet radiation of the sun."

- **Explanation:** This statement is also correct. The ozone layer in the stratosphere plays a crucial role in absorbing the majority of the sun's harmful ultraviolet (UV) radiation, protecting life on Earth.

### Step 3: Analyze Statement 3
**Statement 3:** "The depletion of ozone layer is because of its chemical reactions with chlorofluoroalkanes."

- **Explanation:** This statement is correct as well. Chlorofluorocarbons (CFCs), which are chlorinated gases, deplete the ozone layer through chemical reactions. When CFCs are broken down by UV radiation, they release chlorine atoms that react with ozone, leading to its depletion.

### Step 4: Analyze Statement 4
**Statement 4:** "Ozone absorbs infrared radiation."

- **Explanation:** This statement is incorrect. Ozone primarily absorbs ultraviolet radiation, not infrared radiation. While ozone does have some interaction with infrared radiation, it is not its primary function or characteristic.

### Conclusion
After analyzing all four statements, we find that the incorrect statement is:

**Incorrect Statement:** Statement 4 - "Ozone absorbs infrared radiation."

### Final Answer
The wrong statement is Statement 4: "Ozone absorbs infrared radiation."
