The less stable oxidation states of Cr are:

A

`Cr^(2+)`

B

`Cr^(3+)`

C

`Cr^(4+)`

D

`Cr^(5+)`

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`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.
