Assertion: The spin only magnetic moment of `Sc^(3+)` is 1.73 BM.
Reason: The spin only magnetic momentum in (BM) is equal to `sqrt(n(n+2))`.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Answer

D

Explanation

`S_1`:False , `Sc^(3+)` ion has no unpaired electron `(3d^@ 4s^@)` and thus zero magnetic moment
`S_2`:Magnetic moment is due to 'spin only'=`sqrt(n(n+2))`B.M. value . N is number of unpaired electron(s).
