Learn the basics about Testing for positive ions - part 2.

The last step before learning about the types of reactions in which transition metal complexes participate is to learn about the Hard/Soft Acid-Base Theory. To put it simply, hard means low polarizability, while soft means high...

It explains bonding, properties & limitations of Valence bond theory & crystal field theory of coordination compounds.

It explains nomenclature & various rules for naming the coordination compounds.

We have been learning a lot about a wide variety of compounds, but we haven't really looked much at the transition metals. These also form compounds called coordination compounds, and the types of bonds involved in these compounds is...

We are used to using a theory like VSEPR theory to predict molecular geometry, but unfortunately with coordination compounds, things are not so simple, because of those pesky d orbitals on the central metal atom. Crystal field theory is...
