Question

Magnetic moment of \[\ce{[MnCl4]^{2-}}\] is 5.92 BM. Explain giving reason.

Short/Brief Note
Advertisements

Solution

The magnetic moment of 5.92 BM corresponds to the presence of five unpaired electrons in the d-orbitals of \[\ce{Mn^2+}\] ion. As a result the hybridisation involved is sp3 rather than dsp2. Thus tetrahedral structure of \[\ce{[MnCl4 ]^{2-}}\] complex will show 5.92 BM magnetic moment value.
