Account for the following :
Fluorine forms only one oxoacid HOF
Explain why fluorine forms only one oxoacid, HOF.
Fluorine forms only one oxoacid i.e., HOF because of its high electronegativity and small size.
Cl, Br and I form four series of oxo acids of general formula HOX, HOXO, HOXO2, and HOXO3. In these oxo-adds, the oxidation states of halogens are + 1, + 3, + 5, and + 7 respectively. However, due to high electronegativity, small size and absence of d-orbitals, F does not form oxo-acids with + 3, + 5 and + 7, oxidation states. It just forms one oxo-acid (HOF).
