Q. 27 Magnetic moment of MnCl42- is 5.92 BM. Explain giving reason present.

The magnetic moment 5.92 BM shows that there are five unpaired electrons present in the

d-orbitals of Mn2+ ion, As a result, the hybridisation involved is sp3 rather than dsp2. Thus

tetrahedral structure of MnCl42- complex will show 5.92 BM magnetic moment value.
