The pair of metal ions that can give a spin only magnetic moment of 3.9 BM for the complex [M(H2O)6]Cl2, is -
Multiple Choice Options
- A V2+ and Fe2+
- B V2+ and Co2+
- C Co2+ and Fe2+
- D Cr2+ and Mn2+
Step-by-Step Verified Solution
Magnetic moment = BM
= 3.9
n = 3
no. of unpaired electron = 3
H2O is weak field ligand so no pairing of electrons happens.
Fe2+ = t2g4eg2
Co2+ = t2g5eg2
V2+ = t2g3eg0
M is V, Co.
