Which of the following ions has the highest magnetic moment?

Options

  1. AZn ²⁺
  2. BTi ³⁺
  3. CSc ³⁺
  4. DMn ²⁺

Correct answer

D. Mn ²⁺

Step-by-step solution

= n(n+2) where, n= no. of unpaired electrons. Hence, the ion which has the maximum number of unpaired electron, will show the highest magnetic moment. Mn ²⁺ has maximum 5 unpaired electrons, hence it shows the highest magnetic moment.
