Question

Metal in Wilkinson's catalyst?

• A. \( \text{Fe} \)
• B. \( \text{Ni} \)
• C. \( \text{Ru} \)
• D. \( \text{Rh} \)

Hint:

Wilkinson's catalyst is a rhodium-based catalyst used in hydrogenation reactions.

Answer 1

The Correct Option is D

Wilkinson's catalyst is a homogeneous catalyst used in organic reactions such as hydrogenation. It consists of rhodium (Rh) complex, typically represented as \(\text{RhCl(PPh}_3\text{)}_3\), where \(PPh_3\) is triphenylphosphine. The metal rhodium (Rh) plays a key role in the catalytic process of hydrogenation by facilitating the addition of hydrogen to double bonds. Thus, the metal in Wilkinson's catalyst is Rhodium (Rh).
