  1. Geometrical Isomers of [CoCl2(en)2]+ Objectives: Produce two geometric isomers of an inorganic complex Look for differences in their properties

  2. Geometrical Isomers of [CoCl2(en)2]+ Green Violet

  3. Beer-Lambert Law • A = logI0/ I • A = e L c • molar extinction coeff. x pathlength x concentration e – units of M-1 cm-1 • predicts strength of absorption

  4. fac-mer Geometrical Isomers facial meridional

  5. Optical Isomers: Enantiomers

  6. Magnitude of e’s for trans and cis No inversion center Not forbidden Inversion center Symmetry-forbidden Will e’s of trans absorptions be smaller than those of cis?

  7. Summary 1. Synthesize the two different geometrical isomers of [CoCl2(en)2]+ 2. Analyze different properties of the two isomers, especially wavelengths of absorptions and magnitudes of extinction coefficients
