Choose the correctly paired gaseous cation and its magnetic (spin only) moment (in B.M.)Choose the correctly paired gaseous cation and its magnetic (spin only) moment (in B.M.)

Options

  1. ATi2+,3.87\mathrm{Ti}^{2+}, 3.87 B.M.
  2. BCr2+,4.90\mathrm{Cr}^{2+}, 4.90 B.M.
  3. CCo3+,3.87\mathrm{Co}^{3+}, 3.87 B.M.
  4. DMn2+,4.90\mathrm{Mn}^{2+}, 4.90 B.M.

Correct answer

B. Cr2+,4.90\mathrm{Cr}^{2+}, 4.90 B.M.

Step-by-step solution

Using expression, μ=n(n+2)\mu=\sqrt{n(n+2)} B.M. (where, n=n= no. of unpaired electrons) Choose the correctly paired gaseous cation and its magnetic (spin only) moment (in B.M.)
