Ozone is an extremely powerful oxidizing agent. It is — p Block Elements Chemistry Question

💡 Solution & Explanation

I notice the question appears incomplete — the statement "Ozone is an extremely powerful oxidizing agent. It is..." doesn't show the answer options (A, B, C, D). To provide a complete solution, I need to see what options are given. However, here are the **key facts about ozone ($O_3$) that typically complete this statement**: **Why Ozone is a Powerful Oxidizing Agent:** 1. **High reduction potential**: $O_3 + 2H^+ + 2e^- \rightarrow O_2 + H_2O$, with $E° = +2.07$ V (very positive) 2. **Unstable structure**: The bent, asymmetric $O_3$ molecule readily decomposes, releasing atomic oxygen: $$O_3 \rightarrow O_2 + [O]$$ The nascent oxygen $[O]$ is extremely reactive. 3. **Selective oxidizer**: Unlike chlorine, ozone doesn't form stable compounds with organic matter — it breaks C=C bonds and oxidizes organic compounds rapidly. 4. **No toxic byproducts**: Reduces to $O_2$ only, making it environmentally friendly. **Common correct completions:** - "...more powerful than chlorine" - "...unstable at room temperature" - "...able to disinfect water without harmful byproducts" - "...due to nascent oxygen release" **Please share the complete question with all options so I can confirm why A is correct and address any alternatives.**
