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

Options

  1. A4.90BM4 .90 BM
  2. B3.87BM3 .87 BM
  3. C6.93BM6 .93 BM
  4. D5.92BM5 .92 BM

Correct answer

D. 5.92BM5 .92 BM

Step-by-step solution

The maximum number of unpaired electrons for transition metals =5= 5

or n=5n = 5

Spin only magnetic moment =n(n+2)BM= \sqrt{n\left(n + 2\right)}BM

=5(5+2)=35= \sqrt{5\left(5 + 2\right)} = \sqrt{35}

=5.92BM= 5 .92 BM
