The oxidation number of \(\mathrm{Cr}\) in \(\mathrm{CrO}_{5}\) which has the following structure, is
- A \(+4\)
- B \(+5\)
- C \(+3\)
- D \(+6\)
Answer & Solution
Correct Answer
(D) \(+6\)
Step-by-step Solution
Detailed explanation
The structure of \(\mathrm{CrO}_{5}\) is a butterfly structure where the central chromium atom is bonded to one oxygen atom via a double bond and to four oxygen atoms via two peroxo linkages. In the peroxo linkage, the oxidation state of each oxygen atom is \(-1\). Let the…
