Assertion : Fluorine combines with sulphur to form `SF_(6)` but no other halogen forms hexahalide with sulphur.
Reason : The reactivity of halogens increases as the atomic number increases.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

The correct Answer is:
To solve the given question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Fluorine combines with sulfur to form SF6 but no other halogen forms hexahalide with sulfur." - This is true because sulfur can form a stable compound with fluorine (SF6), which is known as sulfur hexafluoride. Other halogens (Cl, Br, I) do not form stable hexahalides with sulfur due to their larger atomic size and lower electronegativity compared to fluorine. 2. **Understanding the Reason**: - The reason states that "The reactivity of halogens increases as the atomic number increases." - This statement is false. In fact, the reactivity of halogens decreases as we move down the group in the periodic table. Fluorine (F) is the most reactive halogen, followed by chlorine (Cl), bromine (Br), and iodine (I). Therefore, the reactivity does not increase with atomic number. 3. **Conclusion**: - Since the assertion is true and the reason is false, we can conclude that the correct answer to the question is option C: "Assertion is true but reason is false." ### Final Answer: The correct option is C: Assertion is true but reason is false.
