Step 2

Addition of D2 to a carbon-carbon double bond of an alkene is known as deuteration. It occurs in presence of finely divided metals, such as platinum, palladium or nickel, acting as catalysts.

In this reaction, the addition of D2 is always the syn addition which means both deuterium atoms are added on the same side of the double bond.
