Which of the following is called Wilkinson's catalyst ?
  • ✓
    $[(Ph_3P)_3RhCl]$
  • B
    $TiCl_4 + (C_2H_5)_3Al$
  • C
    $(C_2H_5)_4Pb$
  • D
    $[PtCl_2(NH_3)_2]$
✓

Answer

Correct option: A.
$[(Ph_3P)_3RhCl]$
a
Wilkinson's catalyst is $[RhCl(PPh_3)_3]$, Red-violet in colour and has square planar structure. It is used for selective hydrogenation of organic molecules at room temperature and pressure.

$TiCl_4 + (C_2H_5)_3Al$ is Zeigler Natta catalyst.

$(C_2H_5)_4Pb$ is an anti-knocking agent.

cis-platin is used as an anti-cancer agent]
