Current Question (ID: 7942)

Question:

$\text{Assertion (A): Fluorine forms only one oxoacid, HOF.}$\n\n$\text{Reason (R): Fluorine has a small size and high electronegativity.}$

Options:

1. $\text{Both (A) and (R) are True and (R) is the correct explanation of (A).}$ (Correct)
2. $\text{Both (A) and (R) are True and (R) is not the correct explanation of (A).}$
3. $\text{(A) is True but (R) is False.}$
4. $\text{(A) is False but (R) is True.}$

Solution:

$\text{HINT: In oxoacid, the fluorine oxidation state is +1.}$\n\n$\text{Explanation:}$\n\n$\text{Fluorine has very high electronegativity and small size. Due to high electronegativity and small size, fluorine doesn't form the}$\n\n$\text{oxoacids having higher oxidation states such as +3, +5, or +7. So, the +1 oxidation state is shown by fluorine only with}$\n\n$\text{the element oxygen. Thus, it forms only one oxoacid, HOF.}$\n\n$\text{Hence, both assertion and reason are true and the reason is the correct explanation of assertion.}$
