Statement 1: The spin only magnetic moment of Sc3+ is 1.73 B.M. Statement 2: The spin only magnetic moment of an ion is equal to √n(n+2) where n is the number of unpaired electrons in the ion.

Question

Statement 1: The spin only magnetic moment of Sc3+ is 1.73 B.M. Statement 2: The spin only magnetic moment of an ion is equal to √n(n+2) where n is the number of unpaired electrons in the ion. (A) If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1. (B) If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1. (C) If Statement 1 is true but Statement 2 is false. (D) If Statement 1 is false but Statement 2 is true

Statement 1: False; Sc3+ ion has no unpaired electron (3d04s0) and thus has zero magnetic moment. Statement 2: Magnetic moment is due to ‘spin only’ = √n(n+2) value, n is number of unpaired electron(s).

Q. Statement 1: The spin only magnetic moment of $S c^{3 +}$ is $1.73 B . M .$
Statement 2: The spin only magnetic moment of an ion is equal to $n (n + 2)$ where n is the number of unpaired electrons in the ion.

If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1.

If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1.

If Statement 1 is true but Statement 2 is false.

If Statement 1 is false but Statement 2 is true

Statement 1: False; $S c^{3 +}$ ion has no unpaired electron $(3 d^{0} 4 s^{0})$ and thus has zero magnetic moment.
Statement 2: Magnetic moment is due to ‘spin only’ = $n (n + 2)$ value, n is number of unpaired electron(s).

Q. Statement 1: The spin only magnetic moment of Sc3+ is 1.73B.M. Statement 2: The spin only magnetic moment of an ion is equal to n(n+2)​ where n is the number of unpaired electrons in the ion.
