Q.

The highest value of the calculated spin only magnetic moment (in BM) among all the transition metal complexes is :

  1. A

    5.92

  2. B

    3.87

  3. C

    6.93

  4. D

    4.90

Solution

The transition metal atom/ion in a complex may have unpaired electrons ranging from zero to 5. So, maximum number of unpaired electrons that may be present in a complex is 5. Magnetic moment is given as 

BM [no. of unpaired electrons = n)

Maximum value of magnetic moment

5.92 BM
