Concept explainers
Interpretation: The isomers possible in
Concept introduction:
Geometry of coordination compounds: The study of geometry of the coordination compound helps in understanding the physical and chemical property of the compound.
Stereoisomer: The same molecular formula but different with the arrangements of atoms around the metal ion. The Ligands are arranged differently in coordination compounds.
Geometric isomers: stereoisomers that cannot be interconverted without breaking the
Optical isomers: Optical isomers are non-superimposable mirror images.
Plane-polarized light: Light that oscillates in a single plane.

- [CoF6]3- absorbs 700 nm (red) radiation whereas [Co(H2O)6]3+ absorbs 600 nm (orange) radiation. Please draw the crystal field splitting of the above two complexes. Clearly label the orbitals and show the electron occupation.arrow_forwardDoes either cis-[Co(en)2Cl2]+ or trans-[Co(en)2Cl2]- have optical isomers?arrow_forward[Co(H2O)6]2+ (aq) + 4 Cl-(aq )⇆ [CoCl4]2-(aq) + 6 H2O 3. Does the value of the equilibrium constant (K) for this reaction increase, decrease, or remain the same as the concentration of chloride increases? Explain your answer incorporating the definition of an equilibrium constant.arrow_forward
- 8. How many geometrical and/or optical isomers do the following molecules have? Draw a sketch of each isomer and indicate the shape in addition to the types of isomers. a) Pt(NH3)2Br2 b) [Co(phen)2Cl₂]+arrow_forwardSolutions of [Co(NH3)6]2+, [Co(H2O)6]2+ (both octahedral), and [CoCl4]2- (tetrahedral) are colored. One is pink, one is blue, and one is yellow. Based on the spectrochemical series and remembering that the energy splitting in tetrahedral complexes is normally much less than that in octahedral ones, assign a color to each complex.arrow_forwardAre [Co(NH3)4Cl2]Cl and [Co(NH3)4Cl]Cl2 isomers of each other? If so, what type of isomers are they?arrow_forward

(Hint: five geometric isomers are possible.) Draw projection formulas for each isomer, one below the other, and label them A-E. Always check to see whether it is identical, a geometric isomer, or an optical isomer. d.How many of these isomers can exist as a pair of enantiomers? Draw the projection formulas for the mirror images of A-E, and check for superimposability.arrow_forward
