JEE Main Chemistry question

In the isolation of fluorine, a number of difficulties were encountered. Which statement is correct?

(A)The potential required for the discharge of fluoride ions is the highest among halide ions
(B)Fluorine reacts with most glass vessels
(C)Electrolysis of aqueous HF gives ozonized oxygen (rather than )
(D)All of the aboveCorrect

Answer: (D)

Solution

Fluoride ion requires the highest oxidation (discharge) potential of any halide ion, making electrochemical generation very demanding; fluorine attacks ordinary glass apparatus; and electrolysing aqueous HF fails to isolate because the fluorine generated immediately reacts
