The hexaquo manganese(II) ion contains five unpaired electrons, while the hexacyanoion contains only one unpaired electron. Which of the following explains this?
Options
- AThe hexaquo manganese(II) ion undergoes oxidation to form the hexacyanoion, resulting in a change in the numbe
- BThe hexacyanoion has a higher oxidation state for manganese, resulting in a different electron configuration c
- CWater, being a weak field ligand, was not able to pair up the electrons of the 3d subshell, but whereas in the
- DThe coordination number of the manganese(II) ion in the hexacyano complex is higher, causing the change in the
Correct answer
C. Water, being a weak field ligand, was not able to pair up the electrons of the 3d subshell, but whereas in the
Step-by-step solution
Correct Option is : (C) Water, being a weak field ligand, was not able to pair up the electrons of the 3d subshell, but whereas in the case of hexacyano ion the CN − is a strong field ligand and it causes pairing of electrons in the d orbitals
