\(\mathrm{KO}_2\), reacts with water to form \(A, B\) and \(C\).
\(B\) forms \(C\) when it reacts with iodine in basic medium. What are \(B\) and \(C\) respectively?
- A \(\mathrm{KOH}, \mathrm{H}_2 \mathrm{O}_2\)
- B \(\mathrm{K}_2 \mathrm{O}_2, \mathrm{H}_2 \mathrm{O}_2\)
- C \(\mathrm{KOH}, \mathrm{O}_2\)
- D \(\mathrm{H}_2 \mathrm{O}_2, \mathrm{O}_2\)
Answer & Solution
Correct Answer
(D) \(\mathrm{H}_2 \mathrm{O}_2, \mathrm{O}_2\)
Step-by-step Solution
Detailed explanation
(i) When \(\mathrm{KO}_2\) reacts with water, it gives \((A)\), \((B)\) and \((C)\) as follows: (ii) When \((B)\), i.e. \(\mathrm{H}_2 \mathrm{O}_2\) reacts with iodine in basic medium, it gives \((C)\), i.e. \(\mathrm{O}_2\), as shown below : \(\because \mathrm{KOH}\) can not…
