Question

The oxidation no of cr in cro5

Answer 1

Since Cr has only five electrons in 3d orbitals and one electron in 4s orbital. This exceptional value is due to the fact that four oxygen atoms in CrO5are in peroxide linkage. The oxidation no. of Cr in CrO5 is.
x – 2 – 4 = 0
x = + 6.

Answer 2

Answer:

6

Explanation:

Since Cr has only five electrons in 3d orbitals and one electron in 4s orbital. This exceptional value is due to the fact that four oxygen atoms in CrO5are in peroxide linkage. The oxidation no. of Cr in CrO5 is.

x – 2 – 4 = 0

x = + 6.
