QAIPMT-2004-Ch-2602: NEET 2004 Chemistry - Class 12 AIPMT-2004-Ch-2602 Solution: Considering \(H_2O\) as a weak field ligand, the number of…
Considering as a weak field ligand, the number of unpaired electrons in will be (atomic number of Mn = 25)
Multiple Choice Options
- A three
- B five
- C two
- D four
Step-by-Step Verified Solution
In [Mn(H 2 O) 6 ] 2+
Mn +2 = [Ar] 3d 5 4s 0
In presence of weak field ligand H 2 O, there will be no pairing of electrons. So it will form a high spin complex, i.e. the number of unpaired electrons = 5.
