1.

In which of the ion pairs, magnetic property depends on the strngth of ligand present in the complex ?

Answer»

`TI^(3+), V^(3+)`
`Cr^(3+), Mn^(4+)`
`Cr^(2+), Mn^(3+)`
`Mn^(2+), Fe^(3+)`

Solution :`d^(4)` to `d^(7)` configuration are AFFECTED by strength of ligand. `Cr^(2+) to d^(4),Mn^(3+) to d^(4),Mn^(2+) to d^(5),Fe^(3+) to d^(5)`
