Concept explainers
(a)
Interpretation:
The ligands have to be classified as pi-acid or pi-base based on the definition.
Concept Introduction:
Pi-acid or Pi- acceptor:
Ligands having empty orbitals, which can interact with metal d-orbitals for the formation of
Pi-base or Pi-donor:
In coordination chemistry, a pi-donor ligand is a kind of ligand that is capable with filled non-bonding orbital that overlap with metal-base orbitals. If the ligand molecule has pi electrons in d-orbitals they are referred as pi-donor.
Example: F anion will donate this density to the metal atom.
(b)
Interpretation:
The ligands have to be arranged in the order of increasing splitting energy.
Concept Introduction:
Spectrochemical series:
Spectrochemical series is a list of ligands in the order of ligand strength and a list of metal ion based on oxidation number. In crystal field theory, ligands modify the difference in energy between the d orbitals
Series of ligands from weak field to strong field is,

Chemical Principles: The Quest for Insight
- One 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_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_forward
