Question:
The magnetic moment of [MnCl4]2– is 5.92 BM. Explain giving a reason.
Solution:
A magnetic moment of 5.92 BM means there are 5 unpaired electrons because
Magnetic Moment = √ n(n+2)
The geometry tetrahedral with 5 unpaired electrons giving a magnetic moment of 5.92 BM as the four ligands are attached to Mn2+.
