The less stable oxidation state of `Cr` are:A. `Cr^(2+)`B. `Cr^(3+)`C. `Cr^(4+)`D. `Cr^(6+)`

The less stable oxidation state of `Cr` are:A. `Cr^(2+)`B. `Cr^(3+)`C.

1.	The less stable oxidation state of `Cr` are:A. `Cr^(2+)`B. `Cr^(3+)`C. `Cr^(4+)`D. `Cr^(6+)`
Answer» Correct Answer - ACD `Cr^(3+)` is most stable because in aqueous solution it has higher `CFSE` on account of half filled `t_(2g)^(3)` energy level of `3d` orbitals in octahedral spliting.
