Options
- A. A and E only
- B. B and C only
- C. A and D only
- D. B and D only
Answer
D. B and D only
Step-by-step solution
array lcc Ions & No. of unpaired electrons & Configuration \\ Ti ^ 3+ & 1 & 3 d^1 \\ Cr ^ 2+ & 4 & 3 d^4 \\ Mn ^ 2+ & 5 & 3 d^5 \\ Fe ^ 2+ & 4 & 3 d^6 \\ Sc ^ 3+ & 0 & 3 d^0 array Spin only magnetic moment is given by n(n+2) BM Cr ^ 2+ and Fe ^ 2+ will have same spin only magnetic moment.
