Question

Why does fluorine form only one oxoacid?

(a) High electronegativity of fluorine

(b) Large radius of fluorine

(c) Presence of a single valence electron

(d) High electropositivity of fluorine

I have been asked this question in an internship interview.

This is a very interesting question from P-Block Elements in division P-Block Elements of Chemistry – Class 12

Answer 1

Right option is (a) High electronegativity of fluorine

Easiest explanation: Fluorine is the most electronegative element on the periodic table. Due to its high electronegativity and small atomic radius, fluorine only forms one oxoacid, HOF known as hypofluorous acid.
