The value of the spin only magnetic moment for one of the following configurations is 2.84 BM. The correct one is-
A
d5 (in strong field Ligand)
B
d3 (in weak as well as strong. field)
C
d4 (in weak field Ligand)
D
d4 (in strong Ligand field)
Answer
d4 (in strong Ligand field)
Explanation
Solution
The given value of m (spin only)
= (n+2)ān
= 2.84 BM
which corresponds to n = 2. Among the given configurations, d4 system in strong ligand field will have 2-unpained eā in t2g set of orbitals as shown below.
