In \(KO_2\), the nature of oxygen species and the oxidation state of oxygen atom are, respectively
- A Superoxide and \(-1\)
- B Superoxide and \(-1/2\)
- C Peroxide and \(-1/2\)
- D Oxide and \(-2\)
Answer & Solution
Correct Answer
(B) Superoxide and \(-1/2\)
Step-by-step Solution
Detailed explanation
In \(KO_2\), the nature of oxygen species and the oxidation state of oxygen atom are superoxide (superoxide ion is \(O_2^-\)) and \(-1/2\) respectively. Let \(x\) be oxidation state of oxygen. The oxidation state of \(K\) is \(+1.\) Hence \(+1+2(x)=0\) \(2x=-1\)…
