To which of Cu(II) and Zn(II) is Ni(II) most similar regarding formation of hydroxo– and ammine–complexes? Explain.
Ni(II) is very similar to Cu(II) , regarding formation of hydroxo and Ammine Complexes. Because, both Cu(II) and Ni(II) form Octahedral Hydroxo and Ammine complexes, whereas Zn(II) always form Tetrahedral Complexes, due to 0 CFSE. Both Cu(II) and Ni(II) Ammine and Hydroxo Complexes are highly Coloured, whereas Zn(II) Complexes are Colourless.
