Given below are two statements: one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A :\) Flourine forms one oxoacid. Reason \(R\) : Flourine has smallest size amongst all halogens and is highly electronegative In the light of the above statements, choose the most appropriate answer from the options given below.

A Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\).
B Both \(A\) and \(R\) are correct but \(R\) is NOT the correct explanation of \(A\).
C \(A\) is correct but \(R\) is not correct.
D \(A\) is not correct but \(R\) is correct

Verified Solution

Answer & Solution

Correct Answer

(A) Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\).

Step-by-step Solution

Detailed explanation

Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\).

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
