F2 gas can't be obtained by the electrolysis of any F- salt because:
Correct answer: B. Fluorine is the strongest oxidising agent
- A. Fluorine is the strongest reducing agent
- B. Fluorine is the strongest oxidising agent
- C. Fluorine easily combines with atmospheric O2
- D. All
Explanation
Fluorine (F2) is the strongest oxidizing agent, meaning it is more likely to gain electrons rather than lose them. During the electrolysis of F- salts, these ions do not release electrons to form F2 gas due to fluorine's high electronegativity and its tendency to attract electrons. This property of fluorine prevents the formation of F2 gas through this method of electrolysis.Option A is incorrect because fluorine is not a reducing agent. Option C is incorrect because the reactivity with oxygen is not relevant here. Option D is incorrect because it wrongly suggests that all options are correct, while only Option B provides the right explanation.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
