Quiz 10: Chapter 23 (23.1-23.6)

For the 10th and 11th ed. Chapter 23 (23.7) & Chapter 24 (24.1-24.6)

Transition metals, properties of transition metals, lanthanide contraction,
electron configurations and oxidation states (electrons come out of the s
orbitals first), magnetism (understand the different types).

Transition-metal complexes (ligands, complex ions, coordination cmpds),
coordination number, coordination sphere, metal-ligand bonding (Lewis
acid-base rxns), be able to determine oxidation number and coord. number of
the metal in a complexe or coord. cmpd., geometries (often depend on the
ligand - ligands which carry substantial negative charge reduce the the coord.
number, i.e. # atoms dirctly bonded to metal atom)

Know what ligands are and the difference between monodentate, bidentate and
polydentate ligands. Know the names and structures of the most common ligands
(tables 23.4 and 23.5, for the 10th and the 11th ed tables 24.2 and 24.3). For
the bidentate ligands know oxalate, carbonate and ethylenediamine (en). For
the polydenate ligands know ethylenediaminetetraacetate ion (EDTA4-. Know what
celation is.

Isomerism. Know what isomers are. Know the two main groups (structural and
stereoisomers) and the 4 specfic branches from these two main groups: coord.
sphere, linkage, geometric and optical (enantiomers). You need to be able to
draw the cmpds from the formula and the description given (for a coordination
number of 4 I would tell you whether it's tetrahedral, sq. planar). You should
realize when the coord. # is 6 it has to be octahedral. Understand what
enantiomers are (nonsuperimposable mirror images). Know these are chiral and
optically active and one is dextrorotatory (d) and the other would be
levorotatory (l). There's no way to tell which is which simply by looking at
them. However, if I tell you one is (d) then it's enantiomer has to be (l).

Color and magnetism. Understand the color wheel (which will be given) and
complementary colors.


Section 23.6 (crystal field theory):

In this section we've only covered octahedral so far, which I pretty much
finished (I will go over page 8 of part 4 of the notes which summarizes
octaheral field again on Monday). I will give you the spectrochemical series.
You should know what is meant by low field and high field ligands and how this
effects the splitting of the t2 and e orbitals on the metal ion. You should
know what are crystal-field splitting and spin-pairing energy and how to
determine if something will be a high-spin complex or low-spin complex.

For the Thursday quiz you will also need to know about tetrahedral and
square-planar complexes.

You should be able do to homework problems 23.1-23.101 (for Tuesday quiz you
won't have problems dealing with tetrahedral or square-planar complexes).

For those of you using the 11th edition the quiz covers sections 23.7 and
24.1-24.6 and homework problems 23.5-23.6, 23.37-23.48, 23.53-23.56, 23.63,
23.67-23.70, 24.1-24.82

For those of you using the 10th edition the quiz covers sections 23.7 and
24.1-24.6 and homework problems 23.6-23.7, 23.35-23.46, 23.51-23.52, 23.59,
23.64-23.66, 24.1-24.83
