$\ce{H_2C = CH_2 + O_2 ->[Aqueous \; medium] Ch_3CHO}$
What is the catalyst used in the above green reaction?
- Pd(II)
- Pt
- ZnO
- Rh
The Correct Option is A
Solution and Explanation
$H_2C = CH_2 + \frac{1}{2} O_2 \ce{->[PdCl_2/ CuCl_2][\text{Aqueous medium}]} CH_3CHO$
This process is known as Wacker's process.

Alkenes
In organic chemistry, an alkene is a hydrocarbon containing a carbon-carbon double bond.[1]
Alkene is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds.

IUPAC Nomenclature of Alkenes
- An alkene or cycloalkene is indicated by the suffix (ending) ene.
- For the root name, the longest chain must include both carbon atoms of the double bond.
- The root chain must be numbered beginning at the end closest to a double bond carbon atom. If the double bond is in the chain's centre, the nearest substituent rule is used to determine where the numbering begins.
- If the compound contains more than one double bond, it is named with a diene, triene, or equivalent prefix indicating the number of double bonds, and each double bond is assigned a locator number.
