The correct Answer is:
To determine which statement is incorrect, let's analyze each option step by step: 1. **Option A: "Oxidize of nitrogen in atmosphere can cause depletion of ozone layer."** - Nitrogen oxides (NOx), particularly NO2, can indeed contribute to the depletion of the ozone layer. NO2 can catalyze reactions that lead to the breakdown of ozone (O3) in the stratosphere. Therefore, this statement is **correct**. 2. **Option B: "Ozone absorbs infrared rays."** - This statement is **incorrect**. Ozone primarily absorbs ultraviolet (UV) radiation, not infrared rays. The absorption of UV radiation by ozone is crucial because it protects living organisms from harmful UV radiation, which can cause skin cancer and other health issues. 3. **Option C: "Depletion of O2 is due to its chemical reaction with haloalkanes."** - Haloalkanes, particularly chlorofluorocarbons (CFCs), can react with ozone and contribute to its depletion. While the statement mentions O2, the focus is on the reaction of haloalkanes leading to the formation of chlorine radicals, which indeed contribute to ozone depletion. Thus, this statement is also **correct**. 4. **Option D: "None of these."** - Since we have identified that option B is incorrect, this statement cannot be true. Based on the analysis, the incorrect statement is **Option B: "Ozone absorbs infrared rays."** ### Summary of Steps: 1. Analyze each option regarding its correctness. 2. Confirm that nitrogen oxides can deplete ozone (Option A is correct). 3. Identify that ozone absorbs UV rays, not infrared (Option B is incorrect). 4. Recognize that haloalkanes contribute to ozone depletion (Option C is correct). 5. Conclude that since Option B is incorrect, Option D ("None of these") is also incorrect.
