Question

Which of the following is called Wilkinson's catalyst?

• A. [RhCl(PPh₃)₃]
• B. TiCl₄ + (C₂H₅)₃Al
• C. (C₂H₅)₄Pb
• D. [PtCl₂(NH₃)₂]

Answer 1

Answer: (A)

Wilkinson's catalyst is [RhCl(PPh₃)₃], Red-violet in colour and has square planar structure. It is used for selective hydrogenation of organic molecules at room temperature and pressure.
TiCl₄ + (C₂H₅)₃ Al is Zeigler Natta catalyst.
(C₂H₅)₄)Pb is an anti-knocking agent.
cis-platin is used as anti-cancer agent.
