Choose an option

Show full solutionCorrect option: B
Correct answer
Bd2sp3 and paramagnetic

Step-by-step explanation

Magnetic property: Due to presence of one unpaired electrons in 3d shell, [Fe(CN)6]3−  ion is paramagnetic in nature.

​​​​

∴ hybridisation is d2sp3
and due to presence of unpaired e- complex is paramagnetic in nature

∴ hybridisation is d2sp3
and due to presence of unpaired e- complex paramagnetic in nature
