Question

Which of the following does not exist?

• A. \( K^+ + I_2 \)
• B. \( KF + F_2 \)
• C. \( KBr + I_2 \)
• D. \( KF + BrF_3 \)

Hint:

Fluorine is a highly reactive element and does not form stable compounds like \( KF + F_2 \).

Answer 1

The Correct Option is B

The compound \( KF + F_2 \) does not exist as \( F_2 \) is a highly reactive diatomic molecule that does not readily combine with \( KF \).
