Answer to Question #287162 in Organic Chemistry for Chania

Question

Next you must devise a reaction scheme to identify five specific transition metal complex ions and present this by Powerpoint^® (or another suitable presentation medium) to your colleagues. Your presentation must analyse the reactions that transition metal complexes undergo and demonstrate that you understand the concepts of ligand substitution and acidity. The reaction scheme that you propose must allow you to identify your five chosen metal complexes, indicating colours observed and the absence or presence of a precipitate when certain reagents are added. As part of your presentation you must explain the underlying chemistry of your scheme and the reactions involved (ie What is ligand substitution and how does it happen? Why and how do colour changes take place? Why and how does a precipitate form? Why does it sometimes re-dissolve?). Include balanced equations for all reactions.

Answer 1

Five transition metal complex ions are;

FeCl4^- ion

CrCl3 6NH3

AlF6^3- ion

SnCl4^2- ion

Pbl4^2- ion
