Question

Which of the following is called Wilkinson's catalyst?

विकल्प

• [(Ph₃P)₃ RhCl]

• TiCl₄ + (C₂H₅)₃ Al

• (C₂H₅)₄ Pb

• [PtCl₂ (NH₃)₂]

Answer 1

[(Ph₃P)₃ RhCl]

Explanation:

Wilkinson's catalyst is red-violet in colour and has a square planar structure. At room temperature and pressure, it is used for selective hydrogenation of organic molecules. Zieglar-Natta catalyst is TiCl₄ + (C₂H₅)₃ Al. (C₂H₅)₄ Pb is an anti-knocking agent. cis-platin is an anti-cancer agent.
