Question: Wilkinson catalyst is :
$\left[\left(\mathrm{Ph}_{3} \mathrm{P}\right)_{3} \mathrm{RhCl}\right]$ $\left(\mathrm{Et}=\mathrm{C}_{2} \mathrm{H}_{5}\right)$
$\left.\left[\mathrm{Et}_{3} \mathrm{P}\right)_{3} \mathrm{IrCl}\right]$
$\left.\left[\mathrm{Et}_{3} \mathrm{P}\right)_{3} \mathrm{RhCl}\right]$
$\left.\left[\mathrm{Ph}_{3} \mathrm{P}\right)_{3} \mathrm{IrCl}\right]$
Correct Option: 1
Solution:
Wilkinsion catalyst is $\left[\left(\mathrm{ph}_{3} \mathrm{P}\right)_{3} \mathrm{RhCl}\right]$
