Which one of the following liberates oxygen immediately when passed into water?
- A \(\mathrm{F}_2\)
- B \(\mathrm{Cl}_2\)
- C \(\mathrm{Br}_2\)
- D \(\mathrm{I}_2\)
Answer & Solution
Correct Answer
(A) \(\mathrm{F}_2\)
Step-by-step Solution
Detailed explanation
Due to its high reactivity fluoride reacts with water to produce \(\mathrm{O}_2\). \[ 2 \mathrm{~F}_2(g)+2 \mathrm{H}_2 \mathrm{O}(l) \longrightarrow \mathrm{O}_2(g)+4 \mathrm{HF}(a q) \]
