Which of the following statements is not true for halogens ?
- A All form monobasic oxyacids.
- B All are oxidizing agents.
- C Chlorine has the highest electron-gain enthalpy.
- D All but fluorine show positive oxidation states.
Answer & Solution
Correct Answer
(D) All but fluorine show positive oxidation states.
Step-by-step Solution
Detailed explanation
Due to high electronegativity and small size, \(F\) forms only one oxoacid, HOF known as Fluoric (I) acid. Oxidation number of \(F\) is +1 in \(H O F\)
