Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: Fluorine forms one oxoacid. Reason R: Fluorine has smallest size amongst all halogens and is highly electronegative. In the light of the above statements, choose the most appropriate answer from the option given below.
Both A and R are correct and R is the correct explanation of A.
Both A and R are correct but R is NOT the correct explanation of A.
A is correct but R is not correct.
A is not correct but R is correct.
Show Solution
The Correct Option isA
Solution and Explanation
To solve the given question, we need to analyze both the Assertion (A) and the Reason (R) independently, and then decide how they relate to each other.
Assertion (A):
Fluorine forms one oxoacid.
Fluorine forms only one oxoacid, which is hypofluorous acid (HOF). This is due to fluorine's high electronegativity and small size, which prevents the formation of multiple oxoacids. Hence, the assertion is correct.
Reason (R):
Fluorine has the smallest size amongst all halogens and is highly electronegative.
Fluorine indeed has the smallest atomic size among all halogens. It is also the most electronegative element in the periodic table. These properties result in fluorine's unique chemistry, including its ability to form just one oxoacid, HOF. Therefore, the reason is correct.
Analysis:
Both the assertion and the reason are correct.
Fluorine's small size and high electronegativity are crucial reasons for its ability to form only one oxoacid. This makes the Reason (R) a correct explanation of the Assertion (A).
Conclusion:
Based on the analysis, the most appropriate answer is:
Both A and R are correct and R is the correct explanation of A.
