Question

Wilkinson’s catalyst contains

• A. ruthenium(I) in square planar geometry
• B. ruthenium(I) in tetrahedral geometry
• C. rhodium(I) in square planar geometry
• D. rhodium(I) in tetrahedral geometry

Hint:

Wilkinson's catalyst is one of the few examples of rhodium-based catalysts in a square planar coordination environment, useful in hydrogenation reactions.

Answer 1

The Correct Option is C

Step 1: Understanding Wilkinson's catalyst.
Wilkinson's catalyst is a well-known catalyst used in organic chemistry, specifically for the hydrogenation of alkenes. The catalyst consists of rhodium in a square planar coordination environment, with a chloride and phosphine ligands attached.
Step 2: Conclusion.
Wilkinson's catalyst contains rhodium(I) in a square planar geometry.
Final Answer: \[ \boxed{\text{Rhodium(I) in square planar geometry.}} \]
