Question

Write the reaction of ethene with hydrogen.

Answer 1

In the presence of a finely divided catalyst such as nickel, platinum, or palladium, ethene adds hydrogen to undergo catalytic hydrogenation, producing ethane.

\[ \text{CH}_2 = \text{CH}_2 + \text{H}_2 \xrightarrow[\text{or Pt/Pd}]{\text{Ni}} \text{CH}_3 - \text{CH}_3 \]
