Concept explainers
Interpretation:
Thecolors of the given complex compounds are to be determined.
Concept introduction:
Sunlight comprises all thecolors. The objects reflecting all these colors appear white and the objects absorbing all these colors appear black. Any object that absorbs all colors but reflects a particular color is said to possess that color.
The color in coordination compounds can be explained on the basis of crystal field splitting energy by using the expression below:
Here,
The color of a complex compound is the same as the magnitude of the energy of a photon of visible light. The

- Which of the following statement(s) is( are) true? a. The coordination number of a metal ion in an octahedral complex ion is 8. b. All tetrahedral complex ions are low-spin. c. The formula for triaquatrianuninechromiwn(III) sulfate is [Cr(H2O)3(NH3)](SO4)3. d. The electron configuration of Hf2+ is [Xe]4f126s2. e. Hemoglobin contains Fe3+.arrow_forwarda. In the absorption spectrum of the complex ion Cr(NCS)63, there is a band corresponding to the absorption of a photon of light with an energy of 1.75 104 cm-1. Given 1 cm1 = 1.986 1023 J, what is the wavelength of this photon? b. The CrNC bond angle in Cr(NCS)63 is predicted to be 180. What is the hybridization of the N atom in the Ncs- ligand when a Lewis acid-base reaction occurs between Cr3+ and NCs- that would give a 180 CrNC bond angle? Cr(NCS)63 undergoes substitution by ethylenediamine (en) according to the equation Cr(NCS)63+2enCr(NCS)2(en)2++4NCS Does Cr(NCS)2(en)2+ exhibit geometric isomerism? Does Cr(NCS)2(en)2+ exhibit optical isomerism?arrow_forwardIs it possible for a complex of a metal in the transition series to have six unpaired electrons? Explain.arrow_forward
- Five-coordinate coordination complexes are known, including [CuCl5]3 and [Ni(CN)5]3. Write the structuralformulas and identify a plausible geometry for thesecomplexes.arrow_forwardUse the formation constant of [Au(CN)2] in Appendix K to determine the equilibrium concentration of Au+(aq) in a solution that is 0.0071 M CN and 1.1 104 M [Au(CN)2]. Is it reasonable to conclude that 100% of the gold in solution is present as the [Au(CN)2] complex ion? Explain.arrow_forward
