Concept explainers
(a)
Interpretation:
The polydentate ligand and the maximum number of atoms that can bind simultaneously with the centre atom have to be identified.
Concept Introduction:
A polydentate ligand is a ligand that coordinates to a metal center via two or more atoms, forming two or more bonds. This resulting complex is known as a chelate complex.
Example:
EDTA, a hexadentate ligand is an example of a polydentate ligand that has six donor atoms with electron pairs that can be used to bond to a central metal atom or.ion.
(b)
Interpretation:
The polydentate ligand and the maximum number of atoms that can bind simultaneously with the centre atom have to be identified.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The polydentate ligand and the maximum number of atoms that can bind simultaneously with the centre atom have to be identified.
Concept Introduction:

(d)
Interpretation:

Chemical Principles: The Quest for Insight
- Two different compounds are known with the formula Pd(py)2Cl2, but there is only one compound with the formula Zn(py)2Cl2. The symbol py is for pyridine, a mono-dentate ligand. Explain the differences in the Pd and Zncompounds.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_forwardOne of the following nitrogen compounds or ions is not capable of serving as a ligand: NH4+, NH3, NH2. Identify this species, and explain your answer.arrow_forward
- Trimethylphosphine, P(CH3)3, can act as a ligand by donating the lone pair of electrons on the phosphorus atom. If trimethylphosphine is added to a solution of nickel(Il) chloride in acetone, a blue compound that has a molecular mass of approximately 270 g and contains 21.5% Ni, 26.0% Cl, and 52.5% P(CH3)3 can be isolated. This blue compound does not have any isomeric forms. What are the geometry and molecular formula of the blue compound?arrow_forwardWhich of the following ligands is expected to be monodentate, and which might be polydentate? (a) CH3NH2 (b) CH3CN (c) N3 (d) en (e) Br (f) phenarrow_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
