Magnetic moment of [MnCl(4)]^(2-) is 5.9...

Magnetic moment of `[MnCl_(4)]^(2-)` is 5.92 BM. Explain giving reason present.

Text Solution

Verified by Experts

The magnetic moment 5.92 BM shows that there are five unpaired electrons present in the d-orbitals of `Mn^(2+)` ion. As a result, the hydridisation involved is `sp^(3)` rather than `dsp^(2)`. Thus tetrahedral structure of `[MnCl_(4)]^(2-)` complex will show 5.92 BM magnetic moment value.
