Question

$\ce{H_2C = CH_2 + O_2 ->[Aqueous \; medium] Ch_3CHO}$ What is the catalyst used in the above green reaction?

• A. Pd(II)
• B. Pt
• C. ZnO
• D. Rh

Answer 1

Answer: (A)

Pd(II)

Answer 2

$Pd (II)$ (in the form of $PdCl_2)$ catalyst is used in the following reaction :

$H_2C = CH_2 + \frac{1}{2} O_2 \ce{->[PdCl_2/ CuCl_2][\text{Aqueous medium}]} CH_3CHO$

This process is known as Wacker's process.
