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.
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 .✓ Correct
- (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
Answer: (A)
Solution
Assertion A is correct: Fluorine forms only one oxoacid, HOF (hypofluorous acid), due to its high electronegativity and small size. Reason R is also correct: Fluorine is the smallest halogen and the most electronegative element. R correctly explains A because fluorine's small size and high electronegativity prevent it from forming multiple oxoacids, unlike other halogens.
