Concept explainers
Interpretation:
The colouring properties in thegiven coordination compounds are to be explained.
Concept introduction:
The sunlight comprises all the colors. The objects reflecting all these colors appear white and the objects absorbing all these colors appear black. Any object that absorbs all colors but reflects a particular color is said to possess that color.
The colour in coordination compounds can be explained on the basis of crystal field splitting energy by using the expressionbelow:
Here,
The colour of a complex compound is the same as the magnitude of the energy of a photon of visible light. The

- Question: Although both nitrogen and phosphorous take place in Group VA, in complex formation ammonia acts as sigma-donor while PR3 is both sigma–donor and pi-acceptor. In the light of this explanation, show the sigma and pi interactions in [Co(PR3)6]2+ according to MO theory. What makes PR3 a different ligand than ammonia? Do I need to replace t2g orbitals in my diagram? How can I show PR3 ligands using d orbitals?arrow_forwardWhat will be produced when combining molecules that contains two or more groups that donate electrons?
