8. Given what you know about substitution reactions of square planar complexes, explain what would happen in the reaction (Pt(NH3)4]2+ + Cl → Pt(NH3)3CIJ* + NH3 if the entering group were changed from Cl to Br. How would the rate be affected? Write the mechanism for the reaction (be sure to designate a rate determining step) and draw a reaction coordinate diagram.
Copper(I) complexes tend to be tetrahedral rather than octahedral or square planar. Why is this the case? Explain your reasoning.

5) (20 Pts) a) Ni(II) tends to form a variety of complexes w square-planar geometries, while Pd(IID) and PtII) form predominately square-planar complexes, explain using crystal field theory. b) Another striking difference between these three metals is that the NiIV) oxidation state is very rare, while Pd(IV) is more common and Pt(IV) is very common, explain. Show the CFT diagrams for full credit. ith octahedral, tetrahedral and

Group 10 M(II) complexes are often four-coordinate. For Pd and Pt, these molecules are square planar (with few exceptions). However, for Ni(II), tetrahedral complexes are common. Give at least one plausible explanation for this observation.
Rank the 3 complexes (A, B, C) according to their largest Δ.
Three square planar Pt complexes are shown below: (A) [Pt(NH3)4](C1O4)2, (B) Naz[Pt(CN)4], and (C) [Pt(bpy)2](C104)2. H3N2. INH Pt H3N NH3
3. For the following trans effect substitution reactions, predict the square planar products [labelled (a) through ()]. Reminder: the complete list of trans effect ligands can be found in your textbook (Miessler, Tarr, Fischer). Be sure to indicate the arrangement of ligands by using words or pictures.
