Concept explainers
Interpretation:
From the given structures, identical and different structures are to be determined.
Concept introduction:
There are four different arrangements of the ligands in the coordination compounds are shown below:
(a) Cis molecule: - The molecule is said to cis molecule, if two ligands are on the same side of the complex.
(b) Trans molecule: - The molecule is said to trans molecule, if two ligands are on the opposite side of the complex.
(c) Facial molecule: - The molecule is said to facial molecule, if three identical ligands are present on the face of the complex.
(c) Meridional molecule: - The molecule is said to meridional molecule, if three identical ligands are present on the plane of the complex.

- Which of the following compounds can exhibit cis-trans isomerism? O [Fe(CO)2(NH3)2]?* O [Zn(CO)5Br]* [MNCIBR3]?- O [Cr(CO);NO2]²+ O IFe(H2O)6]³+arrow_forwardWhen water ligands in [Ti(H2O)6]3+ are replaced by CN- ligands to give [Ti(CN)6]3-, the maximum absorption shifts from 500 nm to 450 nm. Is this shift in the expected direction? Explain.arrow_forwardWhich is more acidic and why? [Fe(H2O)6]2+ or [Fe(NH3)(H2O)5]2+arrow_forward
- [Cr(H2O)5Br]2+arrow_forwardSuppose you prepared [Co(en)2Cl2]+. How many isomers, geometric and optical, could be formed? Support your answer with structures.arrow_forwardIn [Cr(NH₃)₆]Cl₃, the [Cr(NH₃)₆]³⁺ ion absorbs visiblelight in the blue-violet range, and the compound is yellow-orange. In [Cr(H₂O)₆]Br₃, the [Cr(H₂O)₆]³⁺ ion absorbs visiblelight in the red range, and the compound is blue-gray. Explain these differences in light absorbed and color of the compoundarrow_forward
- Does either cis-[Co(en)2Cl2]+ or trans-[Co(en)2Cl2]- have optical isomers?arrow_forwardName the following compound: [Cr(NH3)4(Cl)2]Cl ∙ 2H2O(s) (Hint: the “∙ 2H2O” part indicates it is a “hydrate” so the very last part of the written name is “dihydrate.”)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
- [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_forwardWhat is the IUPAC name of [Pd(CN)2(en)2][PtCl4]?arrow_forwardWhat is the oxidation number of the metal in [Rh(NH3)5Cl](NO3)2?arrow_forward
