Question

The spin only magnetic moment of Mn³⁺ (Z = 25) in aqueous solution is ____________.

विकल्प

• `sqrt3  "BM"`

• `2sqrt6  "BM"`

• `sqrt6  "BM"`

• `3sqrt6  "BM"`

Answer 1

The spin only magnetic moment of Mn³⁺ (Z = 25) in aqueous solution is `underline(2sqrt6  "BM")`.

Explanation:

The electronic configuration for Mn³⁺ (Z = 25) will be

There are 4 unpaired electrons, so n = 4.

∴ µ = `sqrt("n"("n" + 2))  "BM"`

= `sqrt(4(4 + 2))`

= `2sqrt6  "BM"`
