Concept explainers
(a)
Interpretation:
The wavelength of maximum absorption and the crystal field splitting energy have to be calculated.
Concept introduction:
Crystal field splitting: The energy gap between the splitting of d-orbitals of the metal ion in presence of ligands is known as the crystal field splitting
The fact that colour depends on the ligand allows us to create a spectrochemical series, which ranks the ability of a ligand to split
The relative magnitude of
The spectrochemical series is
(a)

Explanation of Solution
(b)
Interpretation:
The spectrochemical series for the ligand in the Chromium complex has to be written.
Concept introduction:
The fact that colour depends on the ligand allows us to create a spectrochemical series, which ranks the ability of a ligand to split
The relative magnitude of
The spectrochemical series is
(b)

Explanation of Solution
Comparing the energies of the chromium complexes, we find the energy increases in the order:
This is an abbreviated spectrochemical series.
(c)
Interpretation:
The Iron data is affect the oxidation state has to be explained.
Concept introduction:
Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.
The spectrochemical series is
(c)

Explanation of Solution
The higher the oxidation number the greater the crystal field splitting
(d)
Interpretation:
The Cobalt, Rhodium and Iron atom affect the periodic number has to be discussed.
Concept introduction:

- Which of the following statements is false regarding hydrogen gas production? Group of answer choices Steam reforming requires a catalyst. Methanol (CH3OH) can react with water using a ZnO catalyst to form H2(g). Methanol (CH3OH) can react with O2(g) using a Pd catalyst to form H2(g). The reaction between CH4(g) and H2O to form H2(g) requires a temperature of at least 700 oCarrow_forwardWhich of the following forms of hydrogen is the least stable?
