Chemistry - Coordination Chemistry Question with Solution | TestHub
Co-ordination compounds are used as catalyst for many industrial processes. Example include Rhodium complex used for the hydrogenation of alkenes, this catalyst is called as Wilkinson catalyst.
There are four different compounds of with ligand and that are A, B, C and D. Consider the following information.
The possible combination of A, B, C and D
Options:
Answer:
Solution:
Formula: The crystal field splitting energy () is inversely proportional to the wavelength of light absorbed (), since .
Ligand Strength: According to the spectrochemical series, the field strength of the given ligands follows the order: .
Complex Energy Order: Comparing the complexes, the total field strength and splitting energy () increase in the order: .
Wavelength Matching: Therefore, the absorbed wavelength () follows the reverse order (A > B > C > D), matching the values 535 nm > 500 nm > 475 nm > 310 nm respectively.
