Consider the following complex ions: [NiBr6]4-,[Ni(H2O)6]3+ and [Ni(CO)6]3+. Using the Crystal Field Theory, in each case (i)  draw d-orbital electron configurations (ii)  determine the number of unpaired electrons (iii)  predict the magnetic properties (iv)  state and explain the complex is high-spin or low-spin.

[Fe(OH₂)6]²+ is paramagnetic whereas [Fe(CN)6]4 is diamagnetic. Which of the following provides the best explanation for this? As a weak field ligand, H₂O induces a larger A, than CN, which is a strong field ligand. [Fe(OH₂)6]²+ is a positively charged complex whereas [Fe(CN)6]4 is a negatively charged complex. O [Fe(OH₂)6]²+ has fewer paired electrons because the pairing energy is larger than A.。. O [Fe(OH₂)6]²+ is a low spin complex while [Fe(CN)6]4 is a high spin complex.

What is the transition metal-containing product for the following reaction, where [Rh(CO)Br3]2- is a square-planar complex? [Rh(CO)Br3]2-  +  CO(g)  -->  ? Group of answer choices [RhBr4]3- an equal mixture of cis- and trans-[Rh(CO)2Br2]- trans-[Rh(CO)2Br2]- cis-[Rh(CO)2Br2]-
