  • The magnetic moment of [ MnCl_{4} ]^{2-} is 5.92 BM. Explain giving a reason.

The magnetic moment of  \left [ MnCl_{4} \right ]^{2-} is 5.92\; BM. Explain giving reason.

Answers (1)

A magnetic moment of 5.92 BM indicates that there are at least 5 unpaired electrons. The formula for Magnetic Moment =\sqrt{n(n+2)}

As four ligands are attached to Mn^{2+}, therefore the geometry tetrahedral with 5 unpaired electrons gives a magnetic moment of 5.92 BM.
