In conducting the catalytic hydrogenation of an alkene, which catalyst listed is most likely soluble in the reaction medium?
A) Ni
B) Pt
C) Pd
D) Wilkinson's catalyst
E) All of the above are soluble

Question

Quizplus · Accepted Answer

Wilkinson's catalyst (RhCl(PPh3)3) is a soluble homogeneous catalyst, meaning it is dissolved in the reaction medium (usually a solvent). Nickel (Ni), Platinum (Pt), and Palladium (Pd) are typically used as heterogeneous catalysts, meaning they are insoluble and are typically deposited onto a support material (such as charcoal or alumina) which allows them to be suspended in the reaction medium. Therefore, the only soluble catalyst listed is D) Wilkinson's catalyst.
