1.Provide a valid explanation
based on the symmetry properties of molecule for
the following observation:
IR spectrum of
fac-[Fe(CO)3(CN)3] has two strong absorptions
at 2121 and 2096 cm1 , as well as two weaker bands at 2162 and 2140
cm1 . ]
Hint: Answer must contains the
structure of the molecule drawn that shows the geometry of the
molecule, point group, symmetry labels and irreducible
representations and associated spectral characteristics.
2.Provide a valid experimental
method/s that you choose to differentiate between
fac-[Fe(CO)3(CN)3] and
mer-[Fe(CO)3(CN)3]. [The experiments should
be based on symmetry….]Draw the expected results of the experiment
in each case in a TABULAR form
[One type of experimental Result
(with explanation) – 2 points; Additional type of experimental
method – 2 more points]
