Importance And Applications Of Coordination Compounds

Concept: Wilkinson’s catalyst is used for hydrogenation of alkenes.

Step 1: Recall catalyst composition.


Step 2: Identify metal.
Central metal = Rhodium

Step 1: Understanding the Concept:
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body.
Step 2: Key Formula or Approach:
The approach is to identify the specific chelating ligand structurally and medically suited to bind and safely excrete copper ions from the human body.
Step 3: Detailed Explanation:
Wilson's disease is a genetic disorder where excess copper accumulates in the body tissues, particularly in the liver and brain.
To treat this copper toxicity, specific chelating ligands are administered.
D-Penicillamine is a well-known therapeutic chelating agent (ligand) that binds tightly to copper ions, forming a stable, water-soluble complex.
This complex is then safely filtered by the kidneys and excreted in the urine.
Other chelators like EDTA are primarily used for lead poisoning, while Desferrioxamine is used for iron overload.
For copper specifically, D-Penicillamine is the standard choice.
Step 4: Final Answer:
D-Penicillamine is the ligand used to remove excess Cu.
