[FeF6]4- is which type of complex? |
Inner orbital complex Outer orbital complex Double salt None of these |
Outer orbital complex |
In [FeF6]4- ion x + 6(-1) = -4 x - 6 = -4 x = -4 + 6 = 2 Fe2+: [Ar]3d6 As F- is a weaker field ligand. So, it will not involve 3d orbitals by pairing the electrons, but it will use 4d-orbitals of Fe2+ ion making it a outer orbital complex. |
