Solution

The correct option is A 1
CrO5 has oxidation number of Cr as +6. This implies it has two peroxy linkages.
Let x be the oxidation number of Cr in CrO5.
Since the overall
charge on the complex is 0, the sum of oxidation states of all elements in
it should be equal to 0.
Therefore, x+(2)+4(1)=0
or, x=+6
