NEET (UG) 2024 — Question 62

Spin only' magnetic moment is same for which of the following ions?

A. Ti3+\mathrm{Ti}^{3+}

B. Cr2+\mathrm{Cr}^{2+}

C. Mn2+\mathrm{Mn}^{2+}

D. Fe2+\mathrm{Fe}^{2+}

E. Sc3+\mathrm{Sc}^{3+}

Choose the most appropriate answer from the options given below.

  1. Option A:

    B and D only

    Correct
  2. Option B:

    A and E only

  3. Option C:

    B and C only

  4. Option D:

    A and D only

Answer: A

Step-by-step solution

lonsNo. of unpaired electronsConfiguration
T3+{{\text{T}}^{3+}}13d13{{d}^{1}}
Cr2+\text{C}{{\text{r}}^{2+}}43d43{{d}^{4}}
Mn2+\text{M}{{\text{n}}^{2+}}53d53{{d}^{5}}
Fe2+\text{F}{{\text{e}}^{2+}}43d63{{d}^{6}}
Sc3+\text{S}{{\text{c}}^{3+}}03d03{{d}^{0}}

Spin only magnetic moment is given by n(n+2)BM\sqrt{n(n+2)} \mathrm{BM}

∴Cr2+\therefore \mathrm{Cr}^{2+} and Fe2+\mathrm{Fe}^{2+} will have same spin only magnetic moment.
