Concept explainers
(a)
Interpretation: Thestructure of cis-dichloroethylenediamineplatinum(II) needs to be determined.
Concept Introduction:
Stereoisomer of coordination complexes or molecules have same structural formula but different arrangement of bonded atoms or group in 3-D space.
Geometrical isomers are the type of stereoisomers which can be defined as the complexes or molecules which have same structural formula but different orientation of bonded ligands in the plane. They are two types, in trans-isomer, similar ligands are placed in opposite direction whereas in cis-isomer same ligands are placed in the same direction.
(b)
Interpretation: The structure of trans-dichlorobis (ethylenediamine) cobalt(II) needs to be determined.

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_forwardFor each d electron configuration, state the number of unpaired electrons expected in octahedral complexes. Give an example complex for each case. (Two answers are possible for some of these cases.) (a) d2 (b) d4 (c) d6 (d) d8arrow_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_forward
