The oxidation state of Cr in CrO ₅ is
Options
- A-6
- B+12
- C+6
- D+4
Correct answer
C. +6
Step-by-step solution
The structure of CrO ₅ is Oxidation state of Cr is +6 due to the presence of two peroxide linkages, which can be calculated as. In CrO ( O ₂ )₂ , let the oxidation state of Cr be x aligned x +(-1) 4+(-2) & =0 x -6 & =0 x & =+6 aligned
