The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that displacement reactions of chlorine, bromine, and iodine using fluorine are not generally carried out in aqueous solution. **Explanation**: Displacement reactions involve a more reactive element displacing a less reactive element from a compound. Fluorine is indeed more reactive than chlorine, bromine, and iodine. However, the assertion claims that these reactions are not typically performed in aqueous solutions. ### Step 2: Understand the Reason The reason given is that fluorine, being highly reactive, attacks water and displaces the oxygen of water. **Explanation**: Fluorine is the most electronegative element and reacts vigorously with water. Instead of displacing chlorine, bromine, or iodine in an aqueous solution, fluorine reacts with water to form hydrofluoric acid (HF) and oxygen. This reaction can be represented as: \[ 2 \text{H}_2\text{O} + \text{F}_2 \rightarrow 2 \text{HF} + \text{O}_2 \] ### Step 3: Analyze the Relationship Both the assertion and reason are correct. The reason explains why the assertion is true. Since fluorine reacts with water instead of the halogens, it is indeed not practical to carry out these displacement reactions in aqueous solutions. ### Conclusion Both the assertion and reason are true, and the reason correctly explains the assertion. Therefore, the correct answer is: **Option 1**: Both assertion and reason are true, and reason is the correct explanation of assertion. ---
