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

Text Solution

Verified by Experts

The magnetic moment of 5.92 BM corresponds to the presence of five unpaired electrons in the dorbitals of `Mn^(2+)` ion. As a result the hybridisation involved is `sp^(3)` rather than `dsp^(2)`. Thus tetrahedral structure of `[MnCl_(4)]^(2-)` complex will show 5.92 BM magnetic moment value.
