Concept explainers
(a)
Interpretation:
Difference between coordination number and oxidation number is to be defined.
Concept introduction:
When all the ligands and shared paired electron are removed from a coordination compound, the number of charge on central metal is called oxidation number. And a number of ligands are known as co-ordination number.
(b)
Interpretation:
Difference between monodentate and polydentate is to be defined.
Concept introduction:
During metal-ligand complex formation different ligands bind to the central metal ion which is known as coordination compound. Ligands can be of two types monodentate and polydentate.
(c)
Interpretation:
Difference between cis and trans isomers is to be defined.
Concept introduction:
The phenomenon of isomers having different structural composition is known as Structural isomerism. Isomers can be present in different forms known as Cis and Trans-forms.
(d)
Interpretation:
Difference Dextro and Levo rotatory are to be defined.
Concept introduction:
The phenomenon of isomers having different structural composition is known as Structural isomerism. And the isomers can rotate the plane-polarized light and can be divided into Dextro and Levo rotatory.
(e)
Interpretation:
Difference between low spin and high spin complex is to be defined.
Concept introduction:
According to crystal field theory splitting of d orbital occurs which leads to energy emission in the form of light. Here crystal field splitting is presented as

- What is the coordination number of the central metal atom in the following complexes? (a) [Fe(H2O)63+] (b) [Pt(NH3)Br3] (c) [V(en)Cl42] (d) [Au(CN)2+]arrow_forwardFour different octahedral chromium coordination compounds exist that all have the same oxidation state for chromium and have H2O and Cl as the ligands and counterions. When 1 mole of each of the four compounds is dissolved in water, how many moles of silver chloride will precipitate upon addition of excess AgNO3?arrow_forwardClassify each ligand as monodentate, bidentate, and so on.

- a. 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_forwardWhich of these ligands can participate in linkage isomerism:(a) NO2-; (b) SO2; (c) NO3-? Explain with Lewis structuresarrow_forwardOne of the more famous species in coordination chemistry is the Creutz-Taube complex: 5+ (NH3);RuN NRu(NH3)5 It is named for the two scientists who discovered it and ini- tially studied its properties. The central ligand is pyrazine, a planar six-membered ring with nitrogens at opposite sides. (a) How can you account for the fact that the com- plex, which has only neutral ligands, has an odd overall charge? (b) The metal is in a low-spin configuration in both cases. Assuming octahedral coordination, draw the d-orbital energy-level diagram for each metal. (c) In many experiments the two metal ions appear to be in exactly equivalent states. Can you think of a reason that this might appear to be so, recognizing that electrons move very rap- idly compared to nuclel?arrow_forward
