Ncert Exercises & Solutions

The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spin only magnetic moment value of $C r^{3 +}$ ion is:

1.	2.87 BM	2.	3.87 BM
3.	3.47 BM	4.	3.57 BM

NEETprep Answer:

The magnetic momentis associated with its spin angular momentum and orbital angular momentum.
Spin only magnetic momentvalue of

C r^{3 +}

ion is 3

d^{3}

Hence, magnetic moment

(μ) = \sqrt{n (n + 2)} B M

= \sqrt{3 (3 + 2)} = \sqrt{15}

= 3.87 B M
