What is the chelate effect? A) The reaction of en or dien with the hexaaquaniclel (II) cation as results in replacement of the water molecules with the nitrogen-based ligands. B) The name of experiment 23 C) The phenomenon of greater equilibrium constants for the reaction of chelating ligands versus non-chelating ligands. Please explain your thought process of how you know the right answer and why it is not the others. Thank you!
xplain why chelating ligands give more stable complexes than monodentate ligands; use a balanced chemical equation in your explanation. Explain why macrocyclic ligands give more stable complexes than chelating ligands.
(a) What do you understand by chelate effect? llustrate your answer with an (8 marks) (b) For the following equilibrium reactions, predict whether the equilibrium example. constant (K) will be greater or smaller than 1. Briefly explain. (4 marks)
What is an endowment effect? Give an example of such an effect.
What is an example of a tetragonal molecule with sigma donor only ligands?

Why is it necessary to chelate the metal ions from solution during the boiling/lysis step at 100C? What would happen if you did not use a chelating agent such as the InstaGene matrix? 1. 2. What is needed from the cells for PCR? 3. What structures must be broken to release DNA from the cell? Why is it necessary to have a primer on each side of the DNA segment to be amplified? 4. 5. How did Ta?...

iron (III) reacts with chelating agent HL to give a complex FeL3 that is readily soluable in CHCl3.A spectrophotometric study shows that when 1.5x10^-4 M aqueous solution of iron was extracted with CHCl3 containing .0250M HL,the analytical concentration of iron at ph6 in the two phases were 1.0×10^-4 and 5.0×10^-5.What is the distribution coefficient ? What is the distribution coefficient at ph5 ?
