The correct Answer is:
To solve the question, we need to analyze both the assertion (A) and the reason (R) provided. ### Step 1: Analyze the Assertion (A) The assertion states: "Fluorine has lower reactivity." - This statement is **incorrect**. Fluorine is actually the most reactive halogen and is known to be the most electronegative element in the periodic table. Its high reactivity is due to its ability to gain electrons easily. ### Step 2: Analyze the Reason (R) The reason states: "F-F bond has low bond dissociation energy." - This statement is **correct**. The F-F bond in diatomic fluorine (F2) is weak due to the small size of the fluorine atoms, which leads to significant lone pair-lone pair repulsion. This results in a low bond dissociation energy, meaning that it requires less energy to break the bond. ### Step 3: Determine the Relationship Between (A) and (R) Now we need to determine if (R) correctly explains (A): - Since (A) is incorrect and (R) is correct, (R) does not serve as an explanation for (A). ### Conclusion Based on the analysis: - Assertion (A) is incorrect. - Reason (R) is correct. Thus, the correct option is: **If (A) is incorrect, but (R) is correct.** ### Final Answer The correct option is: **If (A) is incorrect, but (R) is correct.** ---
